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.

FLT012A0Z/FLT012A0-SZ: Input Filter Modules
75Vdc Input Voltage Maximum; 12A Output Current Maximum
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 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 metalcased 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. 7. 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 0.1PF 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. 8.

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 9 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. 10.

Example Data Showing Results using the
FLT012A0 Modules
Figure 11 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 dB 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. 12.
Note that the airflow is parallel to the long axis of the
module as shown in Fig. 12.

rated output current of the module.

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 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 5
mm. The maximum nozzle outer diameter, which will safely
fit within the allowable component spacing, is 8 mm max.
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.

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 235oC.
Typically, the eutectic solder melts at 183oC, wets the land,
and subsequently wicks the device connection. Sufficient

Lead Free Soldering
The FLT012A0-SZ 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

(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. 17. 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
