DESCRIPTION

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.
