DESCRIPTION
+Vout
CASE
GND
The EFJ2803 is a high reliability EMI filter for use with the
DAC2800/DHC2800 series of DC-DC converters. 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.
