CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of
sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum
safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating
of 10 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum
dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further
information.

Application Guidelines
Conducted noise on the input power lines can occur as either
differential-mode or common-mode noise currents.
Differential-mode noise 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 high-frequency
nature of common-mode noise is 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 attenuated using a filter
composed of line-to-line capacitors (X caps) and series
inductance, provided by either a discrete inductor or the
leakage inductance of a common-mode choke. In addition to
the differential filtering provided by the filter module, it is
recommended that an electrolytic capacitor be located at the
converter side of the filter to provide additional attenuation of
low-frequency differential noise and to 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 arrangements. The FLT007A0Z series of modules
are optimized 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 shown 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 outputs as
shown. Suitable values for common-mode capacitors C2 and
C3 are in the range between 1000pF to 0.1F are usually
indicated in the DC/DC converter data sheet. These
capacitors need to be rated for the isolation voltage desired
between the input and output sides of the DC/DC converter
module. The recommended power layout of the modules
showing where the two common-mode capacitors are to be
placed is shown in Fig. 6.

Filtering Metal-Case DC/DC Converter
Modules
For metal-case DC/DC converter modules with a case pin, a
different filtering arrangement and layout is recommended.
Figure 7 shows the schematic 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 capacitors C2 through
C5 to the input and output connections of the module. The
shield plane along with the case of the 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 FLT007A0Z 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 meeting EN55022 Class B
limits with sufficient margin.

Thermal Considerations
Power modules operate in a variety of thermal environments;
however, sufficient cooling should always be provided to help
ensure reliable operation.
Considerations include ambient temperature, airflow, module
power dissipation, and the 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 set-up 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 the final circuit-board
assembly process prior to electrical board testing. The result
of inadequate cleaning and drying can affect both the
reliability of a power module and the testability of the finished
circuit-board assembly. For guidance on appropriate
soldering, cleaning and drying procedures, refer to Lineage
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 finish that is compatible with both Pb and Pb-free
wave soldering processes. A maximum preheat rate of 3C/s
is suggested. The wave preheat process should be such
that the temperature of the power module board is kept
below 210C. For Pb solder, the recommended pot
temperature is 260C, while the Pb-free solder pot is 270C
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 Lineage Power representative for more details.
Surface Mount Information
Pick and Place
The FLT007A0-SRZ SMT modules use an open frame
construction and are designed for a fully automated
assembly process. The 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
withstand reflow temperatures of up to 300oC. The label also
carries product information such as product code, serial
number and location of manufacture.
Nozzle Recommendations
The module weight has been kept to a minimum by using
open frame construction. Even so, these modules have a
relatively large mass 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 nozzle outer diameter, which will safely fit
within the allowable component spacing, is 8 mm max.
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 solder reflow profile for each application
board assembly. The following instructions must be
observed when soldering these units. Failure to observe
these instructions may result in the failure of or cause
damage to the modules, and can adversely affect long-term
reliability.
In a conventional Tin/Lead (Sn/Pb) solder process peak
reflow temperatures are limited to less than 235oC.
Typically, the eutectic solder melts at 183oC, wets the land,
and subsequently wicks the device connection. Sufficient
time must be allowed to fuse the plating on the connection to
ensure a reliable solder joint. There are several types of
SMT reflow technologies currently used in the industry.
These surface mount power modules can be reliably
soldered using natural forced convection, IR (radiant
infrared), or a combination of convection/IR. For reliable
soldering the solder reflow profile should be established by
accurately measuring the modules CP connector
temperatures.

Lead Free Soldering
The FLT007A0-SRZ SMT modules are lead-free (Pb-free)
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 cause 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 recommended forced-air-convection reflow profile
based on the volume and thickness of the package (table 4-
2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow profile using Sn/Ag/Cu
solder is shown in Figure. 15.
MSL Rating
The FLT007A0-SRZ SMT modules have a MSL rating of 1.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount packages is
detailed in J-STD-033 Rev. A (Handling, Packing, Shipping
and Use of Moisture/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 life 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
conditions: < 40° C, < 90% relative humidity.
