This filter has been designed to reduce the input line reflected ripple current to within the limit of MIL-STD-461C, CE03. EFJ2803 hybird EMI filters utilize all ceramic capacitors, surface mount magnetics and ultrasonically bonded aluminum wires to provide reliable operation at all operating temperatures while surviving very high G forces. The 8-pin package is hermetically sealed and isolated from the internal circuits. Heat sinking is recommended for full power operation at elevated ambient temperatures. Multiple DC-DC converters may use the same filter, up to the rated throughput current of the filter.
