1 PD-94587A AMH461 SERIES EMI FILTER HYBRID / HIGH RELIABILITY Descriptio The AMH Series EMI filter has bee desiged to provide full compliace with the iput lie reflected ripple curret requiremet specified by CE03 of MIL-STD-461C over the full military temperature rage while operatig i cojuctio with the correspodig AHF series of DC/ DC coverters. These filters are offered as part of a family of high reliability coversio products providig sigle, dual ad triple output voltages while operatig from omial +28 volt iput lie. Other coverters operatig with a similar switchig frequecy will also beefit by use of this device. These EMI filters are hermetically packaged i a seam welded eclosure utilizig axially orieted copper-core pis which miimize resistive DC losses. This package has bee cofigured to complemet the AHF package as a coveiece i system istallatio ad is fabricated with Iteratioal Rectifier s rugged ceramic lead-topackage seal assurig log term hermetic seal itegrity i harsh eviromets. Desiged to meet the deratig requiremets of military ad aerospace use, these devices are maufactured i a facility fully qualified to MIL-PRF-38534, ad are available i two screeig grades. The CH grade iteded for flight use is fully compliat to the requiremets of MIL-PRF for class H. The HB grade is processed ad screeed to the class H Typical Coectio Diagram Features AMH Up to 2.0 A Output Curret Atteuatio > 500 KHz Low Profile Seam Welded Package Ceramic Isulated Copper Core Pis Operatio Over Full Military Temp. Rage No Deratig for -55 C to +125 C requiremets, but does ot iclude elemet evaluatio. The ES grade is processed ad screeed to a lower grade requiremet. Class CH grade ad class HB grade are tested to meet the complete group A test specificatio over the full military temperature rage with o deratig. Variatios i electrical, mechaical ad scree requiremets ca be accommodated. Cotact IR Sa Jose for special requiremets.
