PD-94587 AMH461 SERIES EMI FILTER HYBRID / HIGH RELIABILITY Description The AMH Series EMI filter has been designed to provide full compliance with the input line reflected ripple current requirement specified by CE03 of MIL-STD-461C over the full military temperature range while operating in conjunction with the corresponding AHF series of DC/ DC converters. These filters are offered as part of a family of high reliability conversion products providing single, dual and triple output voltages while operating from nominal +28 volt input line. Other converters operating with a similar switching frequency will also benefit by use of this device. These EMI filters are hermetically packaged in a seam welded enclosure utilizing axially oriented copper-core pins which minimize resistive DC losses. This package has been configured to complement the AHF package as a convenience in system installation and is fabricated with International Rectifier’s rugged ceramic lead-topackage seal assuring long term hermetic seal integrity in harsh environments. Designed to meet the derating requirements of military and aerospace use, these devices are manufactured in a facility fully qualified to MIL-PRF-38534, and are available in two screening grades. The CH grade intended for flight use is fully compliant to the requirements of MIL-PRF-38534 for class H. The HB grade is processed and screened to the class H AMH Features n n n n n n Up to 2.0 A Output Current Attenuation > 60dB @ 500 KHz Low Profile Seam Welded Package Ceramic Insulated Copper Core Pins Operation Over Full Military Temp. Range No Derating for -55°C to +125°C requirements, but does not include element evaluation. The ES grade is processed and screened to a lower grade requirement. Class CH grade and class HB grade are tested to meet the complete group “A” test specification over the full military temperature range with no derating. Variations in electrical, mechanical and screen requirements can be accommodated. Contact IR Santa Clara for special requirements.
