| PD - 94588 ARF461 SERIES ADVANCED ANALOG EMI FILTER HYBRID / HIGH RELIABILITY Description The ARF Series EMI filter has been designed to provide full compliance with the input line reflected ripple current requirement specified by CE03 of MIL-STD461C over the full military temperature range while operating in conjunction with the corresponding ART and ARH 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 ART and ARH package as a convenience in system installation and is fabricated with Advanced Analog's rugged ceramic lead-to-package seal assuring long term hermetic seal integrity in harsh environments. Designed to meet the the derating requirements of MILSTD-975 and manufactured in a facility fully qualified to MIL-PRF-38534, these converters are available in two screening grades. The flight grade is designed, screened and processed for space as specified in MILPRF-38534. The HB grade is processed and screened ARF Features n n n n n n Up to 3.0 Ampere Output Current Attenuation > 40dB @ 100 KHz Low Profile Seam Welded Package Ceramic Feedthru Copper-Core Pins Operation Over Full Military Temp. Range No Derating for -55C to +125C Operation to the class H requirement, but does not include element evaluation. Both grades 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 Advanced Analog 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 . Derate Output Current linearly from 100% at 125C to 0 at 135C. 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 ARF461 Series Available Screening Levels and Process Variations for ARF461 Series MIL-STD-883 Method Flight (No Suffix) -55C to +125C MIL-PRF-38534 2017 1010 2001, 2020 1015 Cond C 3000g Cond A 320 hrs @ 125C (2 x 160 hrs) -55, +25, +125C Cond C 500g -- 160 hrs @ 125C Eng Model (/EM Suffix) -55C to +125C -- Requirement Temperature Range Element Evaluation Internal Visual Temperature Cycle Constant Acceleration PIND Burn-in Interim Electrical @ 160 hrs Final Electrical (Group A) Read & Record Data PDA (25C, interim to final) Radiographic Inspection Seal, Fine & Gross External Visual MIL-PRF-38534 & Specification -55, +25, +125C 2% 2012 1014 2009 Cond A, C -- -- Cond A, C ARF461 Block Diagram +Inpu t +O utp ut Case -In put -O u tpu t www.irf.com 3 ARF461 Series ARF461 Case Style Outline 0.050 0.235 Typ 0.136 D 4 Places 0.375 + Output 0.040 Pin Dia. - Output Case + Input .200 typ 1.950 2.200 0.400 1.67 0.600 - Input 0.375 0.265 1.400 0.275 Max 1.730 0.165 0.300 0.495 Tolerances, unless otherwise specified: .XX .XXX = = 0.010 0.005 Part Numbering A R F 4 61 / E M M odel S cre e n in g A p p lica b le M ilita ry T e st S ta n d a rd /EM - E ng in e erin g M o d el Bla nk- F lig ht (Pro cesse d to C lass K) WORLD HEADQUARTERS: 233 Kansas St., El Segundo, California 90245, Tel: (310) 322 3331 ADVANCED ANALOG: 2270 Martin Av., Santa Clara, California 95050, Tel: (408) 727-0500 Visit us at www.irf.com for sales contact information.
