DESCRIPTION

Interpoint specifically designed the FMH-461™ EMI filter to reduce

the input line reflected ripple current of the following high frequency

DC/DC converters: MHD, MHF, MHF+, MHV, MSA , and MTR

series converters. It will also reduce EMI for several of Interpoint’s

lower frequency converters: MHE/MLP, MHL, MTO, and MTW

series. The FMH-461 filter is ideal for use in applications which must

meet MIL-STD-461C levels of conducted and radiated emissions.

Throughput current is 1.5 amps. At 16 VDC input (low line), the filter

provides 24 watts of throughput power.

FILTER OPERATION

FMH-461 filters are rated for full power operation from –55°C to

+125°C baseplate temperature. Operation is offered up to the

absolute maximum of +135°C with derating as defined in

“Recommended Operating Conditions” on the following page. The

maximum DC insertion loss at full load and nominal input voltage

(28 VDC) represents a power loss of less than 2%.

LAYOUT REQUIREMENTS

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

through a low impedance connection to minimize EMI.

MIL-STD NOISE MANAGEMENT

When used in conjunction with Interpoint converters, the FMH-461

EMI filter reduces input ripple current by 35 dB or greater at 200 kHz

and by at least 50 dB at 500 kHz (see Figures 5 and 6 and electrical

characteristics table). This attenuation gives the converter/filter

combination performance which exceeds MIL-STD-461C’s CE03

test.

1. MSA models may require an inductor in series with the MSA’s positive input.

2 µH is the suggested value.
