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.
MiL-StD nOiSe MAnAgeMent
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.
OPerAting teMPerAture
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.
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.
inSertiOn LOSS
Low DC resistance design results in a maximum power loss of
less than 2% with typical input voltage.
