DESCRIPTION:
The EFJ2803 is a high reliability EMI filter for use with DAC2800/DHC2800/DHD2800 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.
The EFJ2803 hybrid EMI filter utilizes all ceramic capacitors, surface mount magnetics and ultrasonically bonded alumi-
num wires to provide reliable operation at all operating temperatures while surviving very high G forces. The stand-alone
filter's internal components are all passive devices and selected to operate from input voltages up to and including the peak
transient voltage. The filter therefore does not require or utilize transient supression circuitry and is compatible with the
transient specification of a MIL-STD-704 type power bus. When connected to an output device, the output device must be
able to operate from compatible voltages. The filter will attenuate spikes, but the duration and magnitude of the spike must
be within the operating range of the filter and the device connected to it.
The 8-pin package is hermetically sealed and is DC isolated from the internal circuits. Heat sinking is recommended for
full power operation at elevated ambient temperatures.
