FLTR100V10 Filter Module
75 Vdc Input Maximum,
10 A Maximum
RoHS Compliant
The FLTR100V10 Filter Module
is designed to reduce the
conducted common-mode and
dierential-mode noise on input or
output lines of high-frequency switching
power supplies. The module has a
maximum current rating of 10 A. It
provides high insertion loss throughout
the frequency range regulated by the U.S.
Federal Communications Commission
(FCC) and the International Special
Committee on Radio Interference
(CISPR) for conducted emissions.
The module is 51 mm long, 28 mm wide,
and 12 mm high (2.0 in. x 1.1 in. x 0.46 in.)
and mounts on a PC board in a natural
convection or forced-air environment.
Introduction
High-density power modules are usually
designed to operate at a high switching
frequency to reduce the size of the
internal lter components. The small
EMI lters internal to the modules are
often inadequate to meet stringent
international EMI requirements. Many
high-density electronic packaging
techniques can increase the noise
conducted onto the modules’ input and
output lines. For example, the close
proximity of switching components to
the input pins increases internal noise
coupling; and planar transformers,
designed to handle high-power levels
in low- prole packages, have high
interwinding capacitance that can
increase common-mode current levels.
Also, metal substrates used to facilitate
heat transfer from the power train
components to an external heat sink add
to common-mode noise because of the
large capacitance between switching
components and the metal substrate.
Many international agencies specify
conducted and radiated emissions
limits for electronic products. Included
among these are CISPR, FCC, VCCI,
and the new CE specications. Most
agency-conducted noise limits apply
only to noise currents induced onto
the ac power lines in nished products.
European Telecommunication Standard
Instructions (ETSI) are an exception,
applying CE requirements to dc supplies
with cables over three meters long.
Although not required to do so by agency
standards, some system designers apply
the conducted emissions requirements
to subassemblies within the product to
reduce internal interference between
subsystems and to reduce the diculty
of meeting overall system requirements.
To meet these requirements, external
ltering of the power module is often
required. When used in conjunction with
the recommended external components
and layout, the Lineage Power lter
module will signicantly reduce the
conducted dierential and
common-mode noise returned to
the power source. CISPR and FCC
class B requirements can be met
by using the lter as described

Application
Conducted noise on the input power
lines can occur as either
dierential-mode or common-mode
noise currents. Dierential-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
specication, as well as a combination
of the two. An approved measurement
technique is often described, as well.
Dierential-mode noise is best
attenuated using a lter 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 dierential
ltering provided by the lter module,
it is recommended that an electrolytic
capacitor be located at the converter
side of the lter to provide additional
attenuation of low-frequency
dierential noise and to provide a low
source impedance for the converter,
preventing input lter oscillations
and load- transient induced
input voltage dips.
Common-mode noise is best attenuated
by capacitors from power module input
to power module output, capacitors from
each input line to a shield plane (Y caps),
and common-mode chokes. It is
recommended that ceramic
capacitors be added around each
power module from each input and
output pin to a shield plane under
the module. The shield plane should
be connected to the CASE pin.
The GND pin of the lter module is
attached to Y caps within the module.
This pin should be tied to a quiet chassis
ground point away from the power
modules. GND of the lter module should
not be tied to the CASE pin of the power
module since this is a noisy node and
will inject noise into the lter, increasing
the input common-mode noise.
If no quiet grounding point is available,
it is best to leave the lter module GND
pin unattached. Each power system
design will be dierent, and some
experimentation may be necessary
to arrive at the best conguration.
Figure 6 shows a typical schematic of
a power module with lter module and
recommended external components.
Figure 7 is a proposed layout. More
than one power module may be
attached to a single lter module
as long as input current does not
exceed 10 A. Figure 8 shows the
recommended schematic for two power
modules attached to a single lter.
In applications where the addition of
input to output capacitors is undesirable,
do not use C3 and C4 shown in
Figures 6 and 7, and do not use C3,
C4, C8, and C9 shown in Figure 8.
In –48 V applications where the shield
plane and the power module case
must be tied to a signal, remove C1 in
Figures 6 and 7, remove C1 and C6 in
Figure 8, and connect the shield plane
and CASE pin to the VI(+) plane.
In +48 V applications where the shield
plane and the power module case
must be tied to a signal, remove C2 in
Figures 6 and 7, remove C2 and C7 in
Figure 8, and connect the shield plane
and CASE pin to the VI(–) plane.

Application (continued)
Figures 9 and 10 show some experimental results obtained
by using the lter module, together with the recommended
external components shown in Figures 6 and 7.
The JW075A5 module is a lower-noise version of the standard
JW series with internal modications to the power module.
The lower noise of the JW075A5 module is achieved at the
cost of lower eciency, and a reduced maximum power
rating. Measured noise is highly dependent on layout,
grounding, cable orientation, and load characteristics and
will, therefore, vary from application to application.
Thermal Considerations
Filter modules operate in a variety of thermal
environments; however, sucient cooling should
be provided to help ensure reliable operation.
Considerations include ambient temperature, airow,
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 in the data sheet is based
on physical measurements taken in a wind tunnel. The
thermal reference point used for thermal derating curves
presented in Figure 1 is the case of the module. For reliable
operation this temperature should not exceed 100°C.
Other Considerations
It is essential for good EMI performance
that the input lines not be contaminated
with noise after passing through the lter.
Filtered input traces should therefore
be kept away from noise sources such
as power modules and switching logic
lines. If input voltage sense traces must
be routed past the power modules from
the quiet side of the lter module, they
should be ltered at the point where
they leave the quiet input lines. Input
traces should be kept as far away from
output power traces as possible.
The fundamental switching frequency
noise spike can be somewhat reduced
by adding a high-frequency capacitor
of a few microfarads across the
input lines of the lter module.
Adding additional components to the
input lter to improve performance
usually has very limited payback,
and may actually increase the noise
conducted onto the input lines.
Adding Y caps to the input side of the
lter module couples any noise in the
ground plane directly into the input
lines, usually degrading performance.
Adding additional X and Y caps to
the power module side of the lter
module produces low- impedance
loops for high-frequency currents to
ow, possibly degrading performance.
Adding additional common-mode or
dierential-mode ltering to the power
module output leads decreases the
power module output noise, and also
frequently reduces the input noise by
decreasing the noise coupled from
output leads to input leads.
Common-mode output ltering is
particularly important if the load is
tied to chassis ground.
If common-mode ltering is added to
the power module output, ensure that
remote-sense leads sense the output
voltage before the common-mode lter.
Do not use remote-sense on the load
side of an output common-mode lter.
If input noise performance is
unsatisfactory after applying the lter
module as described previously, the
best remedy is to modify the layout and
grounding scheme. It is often useful
to make a model of the power card,
using copper tape and a vector card,
to experiment with various layout
and grounding approaches prior to
committing to a printed-wiring board.

Post Solder Cleaning and
Drying Considerations
Post solder cleaning is usually the nal circuit-board
assembly process prior to electrical board testing.
The result of inadequate cleaning and drying can aect
both the reliability of a power module and the testability
of the nished 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 nish that is compatible with both Pb and
Pb-free wave soldering processes. A Maximum preheat
rate 30C/s is suggested. The wave preheat process should
be such that the temperature of the power module board
is kept below 2100C. For Pb solder, the recommended pot
temperature is 2600C, while the Pb-free solder pot is 2700C
max. Not all RoHS-compliant through-hole products can
be processed with paste-through-hole Pb or Pb-free reow
process. If additional information is needed, please consult
with your Lineage Power representative for more details.
