Throughput Current (A)
FMSA Series™ EMI Filter
The Interpoint® FMSA-461 EMI filter modules have been
designed as a companion for Interpoint MSA Series™ flyback
dc -dc power converters. Multiple MSA power converters can be
operated from a single filter provided the total power line current
does not exceed the maximum current rating of the filter. The
FMSA filter will reduce the MSA’s power line reflected ripple
current to within the limit of MIL-STD-461C, Method CE03, as
shown in the example of Figure 8 on page 9.
The FMSA is fabricated using thick film hybrid techno­logy and
is sealed in a metal package for military, aerospace and other
applications requiring EMI suppression. See case A1, Figure 15
on page 11 for dimensions. The filter uses only ceramic
capacitors for reliable high temperature operation.
Operation
The MSA power converter has an internal 2 µF capacitor across
its input power terminals. See Figure 1 on page 2. When the
MSA and FMSA filters are used together, this capacitor becomes
part of the filter and forms its final LC output section. When 2 or
3 MSAs are used with a single filter, this capacitor becomes 4 µF
or 6 µF respectively, rather than 2 µF, improving the rejection vs.
frequency.

The FMSA filter can also be used with other types of Interpoint
power converters (MHF Series™, MHF+ Series™ and MHE
Series™) to comply with CE03. For MHF, MHF+ and MHE
models, the converter has an LC type line filter such that an
inductor is seen looking into its positive input terminal. For
these converters, it is necessary to terminate the filter with a
capacitor to insure unconditionally stable operation. A capacitor
across the ­filter output terminals of greater than 4 µF or the
optional damping circuit shown on the connection diagram will
be adequate for stable operation. No capacitor is required for the
MSA Series models.
Optional Damping Circuit
The optional damping circuit (Figure 2 on page 2) can be
used to prevent ­filter overshoot caused by MIL-STD-704A 80
volt, or other, transients having rise times of less than 200
microseconds. This damping can be alternately provided with a
1.50 Ω resistor in series with the filter’s positive input where the
additional line loss can be tolerated. For transients with rise times
of greater than 200 microseconds, there is no overshoot and the
damping circuit is not required.
Layout Requirements
The case of the filter must be connected to the case of the
converter through a low impedance connection to minimize EMI.

FMSA/FMGA EMI Input Filters
28 Volt Input - 0.8 AMP
FMGA Series™ EMI Filter
The Interpoint surface mount FMGA-461 EMI filter has been
designed to work with Interpoint surface mount MGA Series™
and MGH Series™ dc-dc converters. Multiple MGA or MGH
converters can be operated from a single FMGA filter provided
the total power line current does not exceed the filter’s maximum
current rating. The FMGA filter will reduce the converter’s power
line reflected ripple current to within the limit of MIL-STD-461C,
Method CE03 as shown in Figure 10 through Figure 14 on page
10. The filter uses only ceramic capacitors for reliable hightemperature operation.
Connection and Operation
Where more than one pin has the same designation (e.g. pins
7, 8, and 9 are Positive Output), all of those pins must be
connected for output performance to meet the specifications.
The MGA Series has an internal 2 µF capacitor on its input
terminals and the MGH Series has an internal 0.47 µF capacitor
across its input power terminals. See Figure 3 on page 4.
When the MGA or MGH converters are used with the FMGA filter,
this capacitor becomes part of the filter and forms its final LC
output section. When 2 or 3 MGA or MGH converters are used
with a single filter, this capacitor becomes larger, improving the
rejection versus frequency.
Surface Mount Package
The FMGA EMI filter can be surface mounted with pick-andplace equipment or manually. It is recommended that the case
be attached with flexible epoxy adhesive or silicone which is
thermally conductive (>1 watt /meter/°K).
Internal components are soldered with SN96 (melting
temperature 221°C) to prevent damage during reflow. Maximum
reflow temperature for surface mounting the FMGA filter is
220°C for a maximum of 30 seconds. SN60, 62, or 63 are the
recommended types of solder. Hand soldering should not exceed
300°C for 10 seconds per pin.
The hermetically sealed metal cases are available in two different
lead configurations. For case dimensions and options, see
Case B ,Figure 16 on page 12 and the solder pad layout of
Figure 17 on page 12.
Layout Requirements
The case of the filter must be connected to the case of the
converter through a low impedance connection to minimize EMI.
Transient Damping
The optional damping circuit shown in Figure 4 on page 4
will prevent ­filter overshoot caused by 80 volt transients with rise
times of less than 200 microseconds. The damping circuit can be
used with a 1.50 Ω resistor in series with the filter’s positive input
where the additional line loss can be tolerated. For transients
with rise times of greater than 200 microseconds, there is no
overshoot and the damping circuit is not required.

0.085 (2.16) 4X
Dimensions in inches (mm)
Tolerance ±0.005 (0.13) for three decimal places ±0.01 (0.3) for
two decimal places, unless otherwise specified.
Please refer to the numerical dimensions for accuracy.
CAUTION:
Internal components are soldered with SN96 (melting
temperature 221°C) to prevent damage during reflow. Maximum
reflow temperature for surface mounting the FMGA filter is
220°C for a maximum of 30 seconds. SN60, 62, or 63 are the
recommended types of solder.
Hand soldering should not exceed 300°C for 10 seconds per pin.
SOLDER MASK NOTES
1. Pad dimensions are for the solder mask. Leads common to
each other can be connected to each other as desired.
2. Ground (case) pins should be connected to the center pad for
improved grounding.
3. Connect "no connection" pins to case ground to reduce EMI.
4. Center pad should not have a solder mask.
5. Adhesive attach is intended to be a surface for soldering the
hybrid to the circuit board.
6. Pre-tin base of converter prior to soldering.
7. If less rotation of case is desired, reduce the width of the large
case pad by 0.020 inches (0.51 mm). Pad length can be
extended 0.010 inches (0.25 mm) towards the case body and an
as-desired dimension away from the case body.
8. Do not exceed 220°C as measured on the body of the
converter (top or bottom).
9. Attach the body of the case to the board with a thermally
conductive adhesive or SN60, 62, or 63 solder. The adhesive
can be electrically conductive as well. It can be applied as an
underfill post solder or dispensed and cured prior or during
solder.
10. In the presence of vibration, to ensure reliable mechanical
attachment, the body of the case should be attached with
adhesive or solder as noted above (note 7). The leads alone do
not provide sufficient mechanical attachment.

Test methods are referenced to MIL-STD-883 as determined by MIL-PRF-38534.
Notes
1. Standard and ES are non-QML products and may not meet all of the requirements of MIL-PRF-38534.
2. All processes are QML qualified and performed by certified operators.
3. Not required by DLA but performed to assure product quality.
4. Burn-in temperature designed to bring the case temperature to +125°C minimum. Burn-in is a powered
