Application Guidelines
Conducted noise on the input po wer lines can occur
as either differential-mode or common-m ode noise
currents. Differential-mode nois e is measured
between the two input lines, and is found mostly at
the low frequency end of the spectrum. This noise
shows up as noise at the fundamental switching
frequency and its harmonics. Common-mode noise is
measured between the input lines and ground and is
mostly broadband noise above 10 MHz. The highfrequency nature of common-mode noi s e i s mostly
due to the high-speed switching transitions of power
train components. Either or both types of noise may
be covered in a specification, as well as a
combination of the two.
Differential-mode noise is best at tenuated using a
filter composed of line-to-line capacit or s (X caps) and
series inductance, provided by either a discrete
inductor or the leakage inductance of a c ommonmode choke. In addition to the differ ential filtering
provided by the filter module, it is recommended that
an electrolytic capacitor be located at the converter
side of the filter to provide additi onal attenuation of
low-frequency differential noise and t o provide a low
source impedance for the converter, preventing input
filter oscillations and load transient induced input
voltage dips.
Open-frame DC/DC converter modules and the older
metal-cased DC/DC converter modules require
slightly different filtering arra ngements. The
FLT007A0Z series of modules are optimi zed for the
newer open-frame series of modules, but can also be
used with older metal-case modules. The main
differences in filtering recommendations between the
two types of modules are in common-mode filtering,
as explained below.
Filtering Open-Frame DC/DC
Converter Modules
For filtering open-frame DC/DC converter modules,
the recommended circuit is sho wn in Fig. 5. In
addition to the input electrolytic filter capacitor C1
(recommended value is a minimum of 100uF and
approximately 1uF/W at power levels above 100W),
common-mode filtering capacitors C2 and C3 should
be connected between the input and out puts as
shown. Suitable values for common-mode capacitors
C2 and C3 are in the range between 1000pF to 0.1µF
are usually indicated in the DC/DC converter data
sheet. These capacitors need to be r ated for the
isolation voltage desired
sides of the DC/DC converter module. The
recommended power layout of the modul es showing
where the two common-mode c apac i tors are to be
placed is shown in Fig. 6.

layout of the FLT007A0Z filter module with
Filtering Metal-Case DC/DC Converter
Modules
For metal-case DC/DC converter modules with a case
pin, a different filtering arrang em ent and layout is
recommended. Figure 7 shows the schem atic
diagram of the recommended circuit. The main
difference with open-frame module is the use of an
isolated shield plane located underneath the module
which is connected through capac i tors C2 through C5
to the input and output connections of the module.
The shield plane along with the case of t he module
serves as a Faraday shield helping reduce EMI. The
corresponding layout for metal-case modules is
shown in Fig. 8.

Example Data Showing Results using
the FLT007A0Z Modules
Figure 9 shows example results obtained using a
QBE025A0B1 DC/DC converter module with the
FLT007A0Z filter module. The QBE025A0B1 module
is operated at an input voltage of 43.2V and output
loading corresponding to an input current of 6.2A, a
level close to the 7A capability of the F LT007A0Z filter
module. A 10nF ceramic capacitor was connected
between Vin(-) and Vo(-) and a 4700pF ceramic
capacitor between Vin(+) and Vo(+). The results show
that the filter module is capable of m eeting EN55022
Class B limits with sufficient margin.

Thermal Considerations
Power modules operate in a variety of thermal
environments; however, suffici ent cooling should
always be provided to help ensure reliable operation.
Considerations include ambie nt temperature, airflow,
module power dissipation, and t he need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel. The test setup is shown in Fig. 10. Note that the airflow is parallel
to the long axis of the module as shown in Fig. 10.

Post solder Cleaning and Drying
Considerations
Post solder cleaning is usually t he final circuit-board
assembly process prior to elect r i c al board testing. The
result of inadequate cleaning and drying can affect
both the reliability of a power modu le and the
testability of the finished circu i t-board assembly. For
guidance on appropriate soldering, cleaning and
drying procedures, refer to Lineag e Power Board
Mounted Power Modules: Soldering and Cleaning
Application Note.
Through-Hole Lead-Free Soldering Information
The RoHS-compliant through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-compliant fini s h that is compatible
with both Pb and Pb-free wave soldering processes.
A maximum preheat rate of 3°C/s is suggested. The
wave preheat process should be such that the
temperature of the power module board is kept below
210°C. For Pb solder, the recommended pot
temperature is 260°C, while the Pb-free s older pot is
270°C max. Not all RoHS-compliant through-hole
products can be processed with paste-through-hole
Pb or Pb-free reflow process. If additional information
is needed, please consult with your Lin ea ge Power
representative for more details .
Surface Mount Information
Pick and Place
The FLT007A0-SRZ SMT modules use an open
frame construction and are design ed for a fully
automated assembly process. T he modules are fitted
with a label designed to provide a large surface area
for pick and place operations. The label meets all the
requirements for surface mount processing, as well as
safety standards, and is able to wit hs tand reflow
temperatures of up to 300
product information such as product code, serial
number and location of manufactur e.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, these
modules have a relatively large m ass when compared
to conventional SMT components. Variables such as
nozzle size, tip style, vacuum pressure and pick &
placement speed should be considered to optimize
this process. The minimum recommended nozzle
diameter for reliable operation is 5mm. The maximum
o
C. The label also carries
nozzle outer diameter, which will safely fit within the
allowable component spacing, is 8 mm max.
Place
Tin Lead Soldering
The FLT007A0-SRZ power modules are lead free
modules and can be soldered either in a lead-free
solder process or in a conventional Tin/Lead (Sn/Pb)
process. It is recommended that the customer review
data sheets in order to customize the s older reflow
profile for each application board ass embly. The
following instructions must be obs erved when
soldering these units. Failure to obs erve these
instructions may result in the failure of or cause
damage to the modules, and can adver sel y aff ect
long-term reliability.
In a conventional Tin/Lead (Sn/Pb) solder process
peak reflow temperatures are limited to less than
o
235
C. Typically, the eutectic solder m el ts at 183oC,
wets the land, and subsequently wicks the device
connection. Sufficient time must be allowed to fuse
the plating on the connection to ensur e a r el iable
solder joint. There are several types of SMT reflow
technologies currently used in t he industry. These
surface mount power modules can be rel i ably
soldered using natural forced convection, IR (radiant
infrared), or a combination of convect ion/IR. For
reliable soldering the solder ref l ow profile should be
established by accurately meas uring the modules CP
connector temperatures.

Lead Free Soldering
The FLT007A0-SRZ SMT modules are lead-free (Pbfree) and RoHS compliant and are both forward and
backward compatible in a Pb-free and a SnPb
soldering process. Failure to observe the instructions
below may result in the failure of or c ause damage to
the modules and can adversely affect long-term
reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for
both Pb-free solder profiles and MSL classification
procedures. This standard provides a r ecommended
forced-air-convection reflow prof i le based on the
volume and thickness of the packag e (table 4-2). The
suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow prof i le using
Sn/Ag/Cu solder is shown in Figure. 15.
MSL Rating
The FLT007A0-SRZ SMT modules have a MSL r ating
of 1.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensit ive surface mount
packages is detailed in J-STD-033 Rev. A (Handling,
Packing, Shipping and Use of Moist ure/Reflow
Sensitive Surface Mount Devices). Moisture barrier
bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages
should not be broken until time of use. Once the
original package is broken, the floor l ife of the product
at conditions of <= 30°C and 60% relative humidity
varies according to the MSL rating (see J-STD-033A).
The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when
stored at the following conditio ns: < 40° C, < 90%
relative humidity.
