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.
