DESCRIPTIOn
Interpoint specifically designed the FMCE-0328TM 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 applications 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 technology 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 temperature 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.
MiL-StD nOiSe MAnAgeMent
When used in conjunction with Interpoint converters, the FMCE0328 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.
OPerAting teMPerAture
The filters are rated to operate, with no degradation of performance, over the temperature range of -55C to +125C (as measured at the baseplate). Above +125C, current must be derated as specified on the following page.
inSertiOn LOSS
Low DC resistance design results in a maximum power loss of less than 2% with typical input voltage.

The case ground connection between the filter and the converter should be as low an impedance as possible to minimize EMI. Direct contact of baseplate to chassis ground provides the lowest impedance.
