DESCRIPTION

The FM-461, FMA-461, and FMB-461 EMI filter modules have been

specifically designed to reduce the input line reflected ripple current

of Interpoint’s MTO, MTW, MHE, MLP, and MFW Series of DC/DC

converters. They are intended for use in applications of high

frequency ( 100 kHz) switch-mode DC/DC converters which must

meet MIL-STD-461C levels of conducted power line noise.

These filters are built using thick-film hybrid technology and are

sealed in metal packages for military, aerospace, and other high-

reliability applications. See Section B8, cases H3, H5, K4, and K6

for dimensions. See Section C2 for screening options.

MIL-STD N

When used in conjunction with Interpoint’s DC/DC converters (see

connection diagram, Figure 2), the input ripple current will be

reduced by 40 dB within the frequency band of 100 kHz to 50 MHz.

This gives the filter/converter combination a performance which

exceeds the CE03 test limit of MIL-STD-461C. The CE03 perform-

ance of a model MHE2805S converter with and without the FM-461

filter is shown in Figures 6 and 7.

OLT

A fast-reacting (1 picosecond) transient suppressor clamps the input

voltage at approximately 47 V, protecting the DC/DC converter from

line induced transients.

The filters are rated to operate, with no degradation of performance,

over the temperature range of –55°C to +85°C (as measured at the

baseplate). Above 85°C, input voltage and current must be derated

as specified in “Derating” on the following page. The maximum

power dissipation of the filters at maximum input current represents

a power loss of less than 3% at typical input voltage.

The case of the filter must be connected to the case of the converter

through a low impedance connection to minimize EMI.
