AMH461

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.

Operation above maximum ratings may cause permanent damage to the device. Operation at maximum ratings may degrade performance and affect reliability. Device can tolerate ± 100 Volt transient whose duration is ≤ 100 ms when RS ≥ 0.5 Ω. Derate Output Current linearly from 100% at 125°C to 0 at 135°C. DC resistance is the total resistance of the device and includes the sum of the input to output resistance and the return in to return out resistance paths. 2 www.irf.com AMH461 Series Typical Filter CE03 Performance AHF2805S CE03 Performance without AMH461 Filter AHF2805S CE03 Performance with AMH461 Filter www.irf.com 3 AMH461 Series Available Screening Levels and Process Variations for AMH461 Series Requirement Temperature Range Element Evaluation Internal Visual Temperature Cycle Constant Acceleration Burn-in Interim Electrical @ 0 hrs Final Electrical (Group A) Read & Record Data PDA (25°C, interim to final) Seal, Fine & Gross External Visual 1014 2009 2017 1010 2001 1015 MIL-PRF-38534 & Specification MIL-STD-883 Method /CH Suffix -55°C to +125°C MIL-PRF-38534 Yes Cond C Cond A 160 hrs @ 125°C -55°, +25°, +125°C 10% Cond A, C Yes /HB Suffix -55°C to +125°C — Yes Cond C Cond A 160 hrs @ 125°C -55°, +25°, +125°C 10% Cond A, C Yes /ES Suffix -55°C to +125°C — Yes Cond B 500g 96 hrs @ 125°C +25°C — Cond A, C Yes AMH461 Block Diagram +Input 1 2 + Output 3 Case - Input 5 4 - Output 4 www.irf.com AMH461 Series AMH461 Case Style Outline .260 0.800 Ø 0.030 Pins 0.050 Typ 0.200 Typ Flanged Package 5 1 1.000 1.700 1.900 1.450 4 3 2 0.350 C 0.920 Ø 0.104 X3 0.331 Max 1.120 0.800 Ø 0.030 Pins .260 R 0.090 Typ Non-Flanged Package 5 1 1.000 1.450 4 3 2 C 0.225 0.331 Max 1.120 Tolerances, unless otherwise specified: .XX .XXX = = ±0.010 ±0.005 Pin Designation Pin No. 1 2 3 4 5 Designation Positive Input Positive Output Case Ground Output Common Input Common Part Numbering AMH 461 F / CH Model Applicable Military Test Standard Screening CH, HB, ES *See chart for details Case Style F = Flange No suffix = No Flange * Note : Refer to the Chart on page 4 WORLD HEADQUARTERS: 233 Kansas St., El Segundo, California 90245, Tel: (310) 252-7105 IR SANTA CLARA: 2270 Martin Av., Santa Clara, California 95050, Tel: (408) 727-0500 Visit us at www.irf.com for sales contact information.
