FMSA SERIES™ EMI FILTER

The FMSA-461 EMI filter modules have been designed as a

companion for Interpoint MSA flyback power converters. Multiple

MSA power converters can be operated from a single filter provided

the total power line current does not exceed the filter maximum

rating. 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 Figures 4 and 5.

The FMSA is fabricated using thick film hybrid technology and is

sealed in a metal package for military, aerospace and other appli-

cations requiring EMI suppression. The filter uses only ceramic

capacitors for reliable high temperature operation.

comply with CE03. For MHF, MHF+, MHD, 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 uncondi-

tionally stable operation. A capacitor across the filter output termi-

nals of greater than 4μF or the optional damping circuit shown on

the connection diagram will be adequate for stable operation. No

capacitor is required for MSA, or DCH models.

PTIONAL

AMPING

IRCUIT

The optional damping circuit (Figure 2) can be used to prevent filter

overshoot caused by MIL-STD-704A 80 V, or other, transients

having rise times of less than 200 μSec. This damping can be alter-

nately provided with a 1.50 Ω resistor in series with the filter positive

input where the additional line loss can be tolerated. For transients

with rise times of greater than 200 μsec, there is no overshoot and

the damping circuit is not required.

PERATION

The MSA power converter has an internal 2 μF capacitor across its

input power terminals. 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, MHF+, MHE, MHD, and DCH series) to

AYOUT

EQUIREMENTS

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

Interpoint’s surface mount FMGA-461™ EMI filter has been

designed to work with Interpoint’s surface mount MGA and MGH

Series DC/DC converters. Multiple MGA or MGH Series converters

can be operated from a single FMGA filter provided the total power

line current does not exceed the filter’s maximum 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 Figures

4 through 7. The filter uses only ceramic capacitors for reliable high-

temperature operation.

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.

ACKAGE

The FMGA EMI filter can be surface mounted with pick-and-place

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 tempera-

ture 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. See case B for dimensions and options.

ONNECTION AND

PERATION

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 its input terminals

and the MGH Series has an internal 0.47 μF capacitor across its

input power terminals. 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.
