| ISO 9001 CERTIFIED BY DSCC 5A EMI FILTER M.S.KENNEDY CORP. 4707 Dey Road Liverpool, N.Y. 13088 BFL2805 (315) 701-6751 FEATURES: Replaces APEX FDB461 All Ceramic Capacitors Surface Mount Magnetics -55C to +125C Operation 60dB Minimum Differential Mode Rejection at 500KHz 5.5 Amps Throughput Current Meets MIL-STD-461C CEO3 Standards For BBF2800 Series DC to DC Converters MIL-STD-704 (A Through E) Power Bus Compatibility MIL-PRF-38534 CERTIFIED DESCRIPTION: The BFL2805 is a high reliability EMI filter for use with 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. The BFL2805 hybrid EMI filter utilizes 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 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. The 12-pin high power dip package allows connection to a heatsink, is hermetically sealed and is isolated from the internal circuits. Heat sinking is recommended for full power operation at elevated ambient temperatures.
