| ISO-9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. 4707 Dey Road Liverpool, N.Y. 13088 5A EMI FILTER BFL2805 (315) 701-6751 HIREL DESIGN REPLACES APEX FDB461 WELDED HERMETIC PACKAGE ALL CERAMIC CAPACITORS SURFACE MOUNT MAGNETICS FEATURES 55 TO +125C OPERATION 50db MINIMUM DIFFERENTIAL MODE REJECTION AT 500 KHz 5.5 AMPS THROUGHPUT CURRENT MEETS MIL-STD-461C CEO3 STANDARDS FOR MSK BBF2800 SERIES DC-DC CONVERTERS MIL-STD-704A THROUGH E POWER BUS COMPATIBILITY 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.
