Safety Precautions

The following are precautions for individual products. Please also refer to the precautions common to EMI Filters,
ESD Suppressors, Fuses, and MR Sensors shown on page EL113 of this catalog.

1. When possible, do not mount 2 mode Noise Filters (hereafter called the fi lters) by fl ow soldering. It is highly
possible that fl ow soldering may cause bridges between the electrodes.

2. Use rosin-based fl ux or halogen-free fl ux.

3. For cleaning, use an alcohol-based cleaning agent. Before using any other type, consult with our sales person
in advance.

4. Do not apply shock to the fi lters or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, their bodies
may be chipped, affecting their performance. Excessive me chanical stress may damage the fi lters. Handle
with care.

5. Store the fi lters in a lo ca tion with a temperature ranging from −5 °C to +40 °C and a relative humidity of 40 % to 60 %,
where there are no rapid changes in temperature or humidity.

6. Use the fi lters within half a year after the date of the outgoing inspection indicated on the packages.

Design and spec ifi cations are e ach subj ect to change w ithout notic e. Ask f actory for t he cur rent technical speci fi c ations before purchase and/or use.

Safety Precautions (Common precautions for EMI Filters, ESD Suppressors, Fuses, and MR Sensors)

• When using our products, no matter what sort of equipment they might be used for, be sure to make a written
agreement on the specifi cations with us in advance. The design and specifi cations in this catalog are subject
to change without prior notice.

• Do not use the products beyond the specifi cations described in this catalog.

• This catalog explains the quality and performance of the products as individual components. Before use, check
and evaluate their operations when installed in your products.

• Install the following systems for a failsafe design to ensure safety if these products are to be used in equip ment
where a defect in these products may cause the loss of human life or other signifi cant dam age, such as damage to
vehicles (automobile, train, vessel), traffi c lights, medical equipment, aerospace equipment, electric heating
appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
Systems equipped with a protection circuit and a protection device

✽

Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a sin gle fault

✽

(1) Precautions for use

• These products are designed and manufactured for general and standard use in general elec tron ic equipment
(e.g. AV equipment, home electric appliances, offi ce equipment, information and communication equipment)

• These products are not intended for use in the following special conditions. Before using the products,
carefully check the effects on their quality and performance, and determine whether or not they can be used.

1. In liquid, such as water, oil, chemicals, or organic solvent

2. In direct sunlight, outdoors, or in dust

3. In salty air or air with a high concentration of corrosive gas, such as Cl

4. Electric Static Discharge (ESD) Environment (except ESD Suppressors)
These components are sensitive to static electricity and can be damaged under static shock (ESD).
Please take measures to avoid any of these environments.
Smaller components are more sensitive to ESD environment.

5. Electromagnetic Environment
Avoid any environment where strong electromagnetic waves exist.

6. In an environment where these products cause dew condensation

7. Sealing or coating of these products or a printed circuit board on which these products are mounted, with

resin or other materials

• These products generate Joule heat when energized. Carefully position these products so that their heat will
not affect the other components.

• Carefully position these products so that their temperatures will not exceed the category temperature range due
to the effects of neighboring heat-generating components. Do not mount or place heat-generating components
or infl ammables, such as vinyl-coated wires, near these products (except Thermal Cutoffs).

• Note that non-cleaning solder, halogen-based highly active fl ux, or water-soluble fl ux may deteriorate the
performance or reliability of the products.

• Carefully select a fl ux cleaning agent for use after soldering. An unsuitable agent may deteriorate the performance
or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water
residues. Otherwise, the insulation performance may be deteriorated.

(2) Precautions for storage

The performance of these products, including the solderability, is guaranteed for a year from the date of ar riv al
at your company, provided that they remain packed as they were when delivered and stored at a tem per a ture
of 5 °C to 35 °C and a relative humidity of 45 % to 85 %. (Micro Chip Fuses: Guaranteed for 6 months from the
date of arrival at your company)
The performance of EMI Filters is guaranteed for 6 months or a year from the out go ing inspection date indicated on
the packages, provided that they are stored at a temperature of -5 °C to +40 °C and a relative humidity of 40 %
to 60 %. Check the guarantee period in the specifi cations. The performance of Thermal Cut offs is guaranteed for a
year from the outgoing inspection date indicated on the packages, provided that they are stored at a temperature of

-10 °C to +40 °C and a relative humidity of 30 % to 75 %.

Even within the above guarantee periods, do not store these products in the following conditions. Otherwise,
their electrical performance and/or solderability may be deteriorated, and the packaging materials (e.g. taping
materials) may be deformed or deteriorated, resulting in mounting failures.

1. In salty air or in air with a high concentration of corrosive gas, such as Cl

, H2S, NH3, SO2, or NO
