AME28461 SERIES
EMI FILTER
HYBRID-HIGH RELIABILITY
Description
The AME Series of EMI filters have been designed to
provide full compliance with the input line reflected
ripple current requirement specified by CE03 of MIL-
AME
STD-461C over the full military temperature range while
operating in conjunction with the corresponding AFL
series of DC-DC converters. These filters are offered
as part of a complete family of conversion products
