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 15 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 highfrequency 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 commonmode 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
FLT012A0 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 0.1μF
are usually indicated in the DC/DC converter data
sheet. These capacitors need to be rated for the
isolation voltage desired
sides of the DC/DC converter module. The
recommended power layout of the modules
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.

Figure 9 shows example results obtained using a
QBVW033 DC/DC converter module with the
FLT012A0 filter module. The QBVW033 module is
operated at an input voltage of 48V and output
loading corresponding to an input current of 8.7A, a
level close to the 12A capability of the FLT012A0 filter
module. Board capacitance was as per
recommendations in the QBVW033 datasheet. The
results show that the filter module is capable of
meeting EN55022 Class A limits with 11 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 setup is shown in Fig. 10. Note that the airflow is parallel
to the long axis of the module as shown in Fig. 10.

Surface Mount Information
Pick and Place
The FLT012A0-SR 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 300
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 5 mm. The maximum
nozzle outer diameter, which will safely fit within the
allowable component spacing, is 8 mm max.

Bottom Side / First Side Assembly
This module is not recommended for assembly on the
bottom side of a customer board. If such an assembly
is attempted, components may fall off the module
during the second reflow process.
Tin Lead Soldering
The FLT012A0-SZ 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
o
235
C. 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 FLT012A0-SZ 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 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. Soldering
outside of the recommended profile requires testing to
verify results and performance.
MSL Rating
The FLT012A0-SRZ SMT modules have a MSL rating
of 2a.
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

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
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 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 solder 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 Lineage Power
representative for more details.
