SCHAFFNER
In today’s world, more electrical energy is being generated at increasing levels of power, and more and more low power energy is being used for the transmission and processing of data. The result is vastly increased ‘electronic smog’ or noise. This noise can disrupt, and even destroy, electronic devices: an unacceptable situation, and shortly an illegal one in certain markets. The electronics
industry must strive to protect equipment against such ‘noise’.
Noise, or interference, travels two ways. Switches - such as semiconductors - can emit interference, and be susceptible to it. The same is true for data processing equipment. The most common method of protection is the use of powerline filters coupled with screening or gasketting materials.
The mains, or powerline, filter is the key element in eliminating mains-borne interference. This filter not only has to meet the requirements of electro-magnetic compatibility (EMC), but safety aspects as well. For some applications, the filter also has to prevent the radiation of classified information from the mains line (‘Tempest’ applications). Other applications require a filter to protect equipment from destructive voltages on the power line, like those caused by lightning or nuclear explosion (NEMP).
Schaffner’s breadth of product range, the high attenuation characteristics of our filters under various load conditions, our dedication to quality - and above all our organization’s unique experience in filter design and manufacturing ­spanning more than 25 years - is your guarantee of excellence.
Total commitment to quality
Schaffner’s aim is to provide our customers with fault­free products. To achieve this, 100% of our products undergo rigorous final
testing. To ensure high quality we have instituted a system which meets all the stringent requirements of the ISO 9001 / EN 29001. The phrase ‘Quality Assurance’ is not just a slogan for us; it is applied in practice, and the Schaffner brand truly stands for reliability and quality.
Schaffner’s single-phase filter range provides an off-the-shelf solution for the vast majority of electronic equipment noise problems. Our standard product range is particularly wide, embracing both chassis-mounting and PCB-mounting types, allowing users to select an optimal choice in both performance and cost efficiency terms.
Chassis-mount types
In general, chassis mount filters provide a higher performance solution, in metal cases for optimum connection to earth and good high frequency performance. With the space available for up to three circuit stages for attenuation of noise, users can usually find an option with the performance to provide an off the shelf solution for even the most difficult of EMC problems (to retrofit an EMC solution to an existing design for instance). Schaffner offers chassis-mounting versions for a very wide range of power levels - from less than 1A to 55A - covering a majority of higher power office equipment and low to medium power industrial applications.
At the lower power levels, users have the additional choice of opting for a PCB-
mounting version (see following section), or an IEC inlet type which typically handle currents of up to 6-10A and are ideal for small office and industrial equipment. The associated IEC 950 specification is a key safety requirement for computer and office/business equipment, developed to provide a consistent world standard, which in turn simplifies the certification process. The standard specifies requirements intended to ensure safety against electrical and fire hazards for the operator and layman who may come into contact with the equipment, and where specifically stated, for service personnel. IEC 950-compliance is required for products shipped in Europe, and has either already become - or is in the process of becoming - a de-facto standard in all other world markets. It has been adopted by European countries under EN60950, and by the USA under UL 1950. Two filter families in this catalogue are available with IEC inlets, one of which is compliant with IEC 950 (request separate IEC inlet/IEC 950 catalogue for full details of Schaffner’s range).
PCB-mount types
PCB filters are designed for compactness and ease of assembly, and avoid the need for extra mounting components and installation operations necessary with chassis styles, but at the expense of finite available space for filtering circuitry. Consequently, they typically offer just a single stage of attenuation, with limitations on the maximum power handling
capability (up to 6.5A current ratings). This typically makes these filters ideal for those companies who have planned for EMC protection throughout the equipment design process, and are completing equipment protection with these low cost components. When designing these components in, care needs to be taken to provide a low impedance connection to earth, and to minimize the potential for any noise

Time to market
The key reasons for choosing ready-made filters are convenience, compactness and cost. Although you can design your own mains inlet and filter using discrete components, or have a custom solution designed and assembled for you, the timescales involved in getting safety approvals will often rule this approach out, especially for higher volume products such as photocopiers which necessitate very fast design cycles.
Ready-made chassis- and PCB-mount filters provide a convenient single-source solution, with the additional benefits of custom-engineered housings for compactness. The following guide to
Schaffner’s single-phase products - with brief details on key parameters - will help you to identify one or more filters for closer review of specifications (there are some 170 options available in the total range). From this initial selection, a review of the circuit diagram and detailed specifications in the following pages will tell you if the module is suitable for your application, allowing you to choose a unit (or units) for trial.
Schaffner is one of the world’s leading suppliers of EMC equipment, and our extensive experience allows us to offer one of the widest EMC filtering ranges available - spanning both general­purpose and specialist needs like TEMPEST. This breadth of range greatly assists designers, allowing optimum
choices to be made, whether the need is for maximum performance or lowest cost.
Our worldwide organization - with its numerous application engineering teams ­will gladly help your engineers select and trial suitable power line filters, and provides an efficient support structure to assist multi-national organizations with dispersed design and manufacturing facilities.
As a review of this catalogue will show you, Schaffner designs power line filters using high grade components in order to optimize reliability. And we construct modules under the control of the most advanced quality system. Whichever power line filter you choose, you can rely on Schaffner’s quality.

Rapid selection Using the current rating and attenuation performance indicators, together with the major features shown on the right, this table allows you to quickly identify a ‘short list’ of filter families which are potentially suitable for your application, for subsequent detailed investigation using the technical specifications on the following pages.
This section introduces the standards and regulations associated with EMC protection, and provides detailed information to help you understand filter design and specifications. It will help you identify for your applica­tion the right specifications and type of filter.
Interference protection standards
Until recently most countries have had their own regulations and standards governing electro-magnetic interference (EMI) or radio frequency interference (RFI). However, on the 1 January 1992 the European Directive 89/336/EMC on electro-magnetic compatibility (EMC) came into force. This directive brings a common approach to EMC to every member state of the European Union. Common standards will be used throughout Europe to ensure that technical trade barriers are removed. As well as controlling EMI emissions from equipment, the directive also calls for equipment to be immune to external electro-magnetic disturbances.
The task of elaborating the standards to be used has been given to the European organisation called CENELEC. The member countries of CENELEC are:
Austria Italy Belgium Luxembourg Denmark Netherlands Finland Norway France Portugal Germany Spain Greece Sweden Iceland Switzerland Ireland United Kingdom
Most of the European standards will be based upon international standards from CISPR and IEC. The numbering system used in the European standards is:
EN xx yyy
EN = European Norm. xx = 50 denotes that the standard is a standard of CENELEC origin; xx = 55 means the standard is based on a CISPR standard yyy; xx = 60 means the standard is based on an IEC standard yyy.
Once the European standard is complete the individual members of the European Union will produce national harmonised standards and will usually give their harmonised standard a national number, eg the British harmonised standard of EN 55011 is BS EN 55011.
Types of standards: Basic standards
describe the general and fundamental rules for meeting the requirements. Terminology, phenomena, compatibility levels, measurement, test techniques and classification of EM environments are so described within.
Generic standards refer to specific
environments. They set minimal EMI levels which equipment in these environments must meet. Where no product specific standards exist then the generic standards are to be used. Generic standards describe household and industrial EMI environments.
Products standards are for specific
products or product groups. These standards are coordinated with the generic standards.
In countries outside Europe other standards will be used, such as the FCC in the USA. Table 1 shows the main European standards.
Permissible noise limits
The various standards set down limits for conducted EMI emissions. These limits are measured in voltage and given in dBµV where 0dB is 1µV. The interference is measured using measurement equipment which has defined bandwidths and receivers. The two receivers used are a quasi-peak detector, and an average detector.
To ensure repeatability of the measurements, the impedance of the mains supply must be constant. The standards calls for a defined artificial mains network - sometimes called a line impedance stabilisation network (LISN) ­which gives a defined impedance to the noise and also helps filter any noise on the mains which may affect the measurements.
Figure 1 shows the limits of EN 50081-1 the European generic standard for residential, commercial and light industrial environments, and Figure 2 of EN 50081-2, the European generic standard for the industrial environment.
Above 30MHz, radiated noise interference is measured instead of conducted noise. This takes place on an open field test site using defined antennas.

Interference sources and spectrums
The most common source of conducted EMI is power electronic products such as switched mode power supplies (SMPS), pulse width modulated (PWM) frequency converters or motor drives, and phase angle controllers.
The emissions spectrum typically starts off very large at low frequency and rolls off as frequency increases. The point at which the noise falls below the permitted limits depends on several factors, the most important being the frequency of operation and the rise time of the semiconductor devices.
Interference spectrums generated can be either continuous, as in the case of phase angle controllers, (Figure 3) or discrete which is typical of the SMPS (Figure 4).
Figure 3. Continuous spectrum
Figure 4. Discrete spectrum
Interference propagation
EMI can propagate by two means:
• by radiation - where the energy can be coupled either through magnetic or electric field, or as an electro-magnetic wave between the source and the victim
• by conduction - where the EMI energy will propagate along power supply lines and data cables
Radiated and conducted EMI cannot be thought of as totally separate problems, because noise conducted along a cable may be radiated as the cable acts as an antenna. The radiation will increase as the cable length becomes comparable to the wavelength of the noise. Also, the cable will act as a receiving antenna and pick up radiated interference.
Below around 150MHz, the most efficient radiating devices in a system are usually the power supply and data cables. Proper filtering of these cables will reduce radiation due to the cables as well as conducted interference.
Above around 150MHz, PCB tracks and short internal cables will start to become efficient antennas. To reduce this radiation a PCB should be laid out to reduce track length and loop areas; ground planes should be used if possible. Decoupling of digital ICs is very important and shielding may be necessary.
Interference types
To understand the problems associated with conducted EMI it is first necessary to understand the two modes of conducted noise: differential mode (or symmetrical mode) and common mode (or asymmetrical mode). Differential mode interference creates a voltage between the phases of the system and is independent of earth; the differential mode currents
flow along one phase and returns along another phase (Figure 5).
Common mode noise creates a voltage between each phase and the earth. The common mode currents flow from the noise source to the earth (usually via a parasitic capacitance) along the earth path and returns along the phases. (See Figure
6) A power line filter must be designed to attenuate both common mode and differential mode interference.

Mains filters
Maximum power transfer occurs when source and load impedances are matched. A power line filter is an inductor-capacitor network that aims to cause maximum mismatch between impedances, and therefore reduces the amount of EMI power to be transferred from the noise source onto the power line cable. Figure 7 shows a typical single-phase power line filter.

The inductors L1 and 2 are usually wound
- in a current compensated fashion - on a toroidal core. This winding method allows flux due to differential mode currents and mains currents to cancel each other, while common mode currents will be added together. This gives a large inductance to common mode currents and ensures that the inductor will not be saturated by the large magnetic flux produced by the mains current.
The capacitors placed between the phases, known as ‘X’ class capacitors must offer a high pulse voltage rating and are used to attenuate differential mode interference. The capacitors between the phase lines and earth, known as ‘Y’ class capacitors must have a more stringent rating and are used to attenuate common mode interference. The value of the Y capacitor is restricted by the permissible leakage current allowed. The maximum leakage current is governed by standards and regulations and depends upon the type of equipment. The leakage current is given by:
I
L
=2· π·U·f·c
where I
L
is the leakage current; U the voltage across the capacitor; f the frequency of the mains voltage across the capacitor, and c the capacitance.
Mains filters should be mounted as close as possible to power entry so that high frequency interference does not bypass the filter. IEC inlet modules are ideally suited for this task.
To achieve higher attenuation or an increase in the effective working frequency range more complex filters than the one shown in Figure 7 can be made using more common mode or differential mode inductors and capacitors.
Insertion loss
The insertion loss characteristics for each filter shown on the datasheets, are measured in accordance with CISPR 17. Two test conditions are employed: one using 50termination impedances, the other using an input impedance of 0.1 and an output impedance of 100(and reverse conditions). Both test methods can be found in section 4.2 of CISPR 17,
and in ‘CISPR 17 Measurements’, a document published by Schaffner and available on request.
In the 50test condition, two sets of insertion loss curves are given. One is common (asymmetrical) mode insertion loss. The other one for differential mode interference.
In general, Schaffner filters perform against common mode interference in the manner shown by the 50insertion loss tests. But in differential mode, the 50is not representative of effective performance. Therefore Schaffner includes the 0.1/100differential mode test to show how a filter will perform in real life situations.
For this 0.1/100test condition, only differential mode insertion loss is given. In this test, mismatched impedances illustrate effective filter performance in a piece of equipment.
Both types of insertion loss testing is carried out without load current. In equipment under load, the inductance ­and therefore the insertion loss - may change due to saturation. To allow for this Schaffner measures the inductance variation with current. A typical filter has an inductance variation as shown in Figure
8. CISPR17, and/or the application note ‘Everything you wanted to know ...’ can provide more detailed information.

temperature of 40°C. Current at other temperatures is shown in the derating curve, or can be ascertained by the formula:
I = I
N
(85 - θ)/45
Voltage ratings
The maximum rated voltage is 250V at 50/60Hz unless otherwise stated on the individual datasheets. Use of capacitors within Schaffner filters which conform to IEC 384 - 14 permit operation at voltages of 10% above this value.
High voltage testing
The high voltage rating of our filters is devided into two specifications, one for type testing and one for production testing. This is in accordance with guidelines laid down in various IEC recommendations. Type testing shall be a minimum of 2121 VDC for a minimum of 60 seconds between all terminals. However, the discharge resistor inside the filter shall be removed for this test according to IEC recommendations. All values given in this catalogue are 100% production tests for a minimum of two seconds. Repetition of voltage tests shall not exceed 80% of the specified values.
Leakage current
The leakage current to ground for each type is given as a maximum value per phase, at 230V/50Hz.

Flammability class All filters in this catalogue are UL 94V2 or UL94V0.
MTBF figures In addition to safety approvals, Schaffner filters also have the high reliability shown in the MTBF (mean time between failure) values given for each filter family. This is the lowest typical value for any filter in the particular family and is calculated according to Mil-HB 217-F, for maximum rated current and voltage in an ambient temperature of 40°C. MTBF is stated in hours.
Components The component values given in the detailed product pages are nominal. The value of inductors and capacitors can vary from this nominal value. The tolerance and test conditions for these components is shown in the following table:

Filters with a greater temperature range, for special applications and for military use, are available on request.
Filters with earth line chokes
It is possible to get interference induced on all cables of a system simultaneously. In this case the same noise will also be induced onto the earth cable. A standard filter will reduce the noise on the phase lines but not on the earth. The noise on the earth line will then be able to enter the equipment and may cause the equipment to malfunction. To reduce this interference earth line chokes may be fitted or incorporated into the filter. The earth line choke will also provide extra attenuation for normal common mode currents.
Care must be taken not to bypass earth line chokes in systems. For example a PC may have a filter with an earth line choke fitted, if this PC is connected to a printer that is powered from the mains supply, and if the printer does not have an earth line choke, the noise may find a path from the mains into the printer and along the data cable into the PC bypassing the earth line choke in the PC.
Filters for medical equipment
For enhanced safety in medical applications, Schaffner offers ‘B’ versions of many of its filters, offering lower leakage current (3µA typical), a discharge resistor, and higher potential test values (for example FN 326B).
Special filters for NEMP
A nuclear electro-magnetic pulse (NEMP) is a high intensity, short duration, electro­magnetic field produced as a result of a nuclear explosion outside the atmosphere (exo-atmospheric). The most critical threat for technically highly developed nations is an exo-atmospheric burst (at an altitude of more than 40 km) producing a NEMP inducing in antennas, power transmission networks etc, such high voltages and currents that it may leave a whole continent without power, telephone or radio communications. Electronic equipment can be protected against a NEMP if it is placed in special room or housing which screen it from the electro-
magnetic fields, and if all feed lines to these areas are protected with voltage limiting devices such as varistors, gas discharge tubes and suppressor diodes.
Special filters for TEMPEST
Telecommunication or data processing equipment can radiate signals, or propagate them along power lines, providing a mechanism for unauthorised persons to access classified information. The study and blocking of such sensitive signals is known as TEMPEST. Mains filters with high attenuation over a large frequency range are necessary. An optimum filter solution can only be found by an exact specification of requirements. The FN 700Z filter series has been used in many TEMPEST applications. Other suitable filters are available on request.
Customer-specific filters
Schaffner’s standard range of filters cover the majority of customers’ requirements. But depending on the application, specific criteria might need to be considered. With our many years of experience, as well as the flexibility and capability of our five development centers located throughout the world, Schaffner can offer companies an efficient and reliable custom engineering service. To date, Schaffner has produced over 4000 custom filters, ranging from 0.1 amps up to 1200 amps, from a matchbox size to rack mount designs, with up to 23 input connections, used in all forms of environments from offices to submarines to factories to military armoured vehicles.

The FN 406 PCB-mounting EMC filter offers high performance in an exceptionally compact form, and is ideal for equipment applications where space is at a premium. With a footprint of just 15 x 45 mm, it greatly reduces the PCB area required compared with using discrete components, with a height profile which does not exceed the capacitors and transformers typically used in circuitry such as switched mode power supplies. Performance is also enhanced, thanks to an aluminium housing
- providing excellent RF shielding to protect against coupling effects from nearby components.
