DESCRIPTION

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 alumi-

num wires to provide reliable operation at all operating tem-

peratures 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.
