DESCRIPTION
The BFL2805 is a high reliability EMI filter for use with MSK
BBF2800 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.
BFL2805 hybrid 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 12-pin high profile dip package allows connection to a
heatsink and is hermetically sealed and isolated from the
internal circuits. Heat sinking is recommended for full power
operation at elevated ambient temperatures.
