DESCRIPTIOn

Interpoint specifically designed the FMCE-0328™ EMI filter to

reduce the input line reflected ripple current of the following high

frequency DC/DC converters: MTR, MHF+ and MHV Series

converters. These filters are intended for use in 28 volt applica-

tions which must meet MIL-STD-461C CE03 and CS01 and/or

MIL-STD-461D, E and F CE102 and CS101 levels of conducted

emissions. At 50 VDC input (high line), the filter provides 150

watts of throughput power.

The FMCE-0328 filters are built using thick-film hybrid tech-

nology and are hermetically sealed in metal packages for military,

aerospace, and other high-reliability applications. Only ceramic

capacitors are used in the filters to ensure reliable high tempera-

ture operation.

The filters are offered with standard screening, “ES” screening,

or fully compliant to “883” MIL-PRF-38534 Class H screening.

Standard microcircuit drawings (SMD) are available.

When used in conjunction with Interpoint converters, the FMCE-

0328 filters reduce input ripple current within the frequency band

of 100 kHz to 50 MHz. When used with an Interpoint converter,

performance exceeds the CEO3 test of MIL-STD-461C and

meets the requirements of CS01 of MIL-STD-461C. These filters

also meet CE102 and CS101 of MIL-STD-461D, E and F.

The filters are rated to operate, with no degradation of perfor-

mance, over the temperature range of -55°C to +125°C (as

measured at the baseplate). Above +125°C, current must be

derated as specified on the following page.

Low DC resistance design results in a maximum power loss of

less than 2% with typical input voltage.
