PD-94588A ARF461 SERIES 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-STD-461C 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 International Rectifier’srugged 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 screenedto 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. 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 -55°C to +125°C Operation 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. 3. 4. 2 www.irf.com ARF461 Series Mechanical Outline 0.050 0.235 Typ 0.136 D 4 Places 0.375 5 0.040 Pin Dia. 4 3 .200 typ 1.950 1 0.400 1.67 2.200 0.600 2 0.375 0.265 0.165 1.400 0.275 Max 0.300 0.495 1.730 Notes: 1) All dimensions are in inches 2) Tolerance, unless otherwise specified: .XX = ± 0.010 .XXX = ±0.005 Block Diagram +Input 1 Input Return 2 5 +Output 3 Case 4 Output Return Pin Designation Pin # Designation 1 + Input 2 Input Return 3 Case Ground 4 Output Return 5 + Output Note: Input and output returns are internally connected www.irf.com 3 ARF461 Series Device Screening Requirement MIL-STD-883 Method Temperature Range Element Evaluation No Suffix EM -55°C to +125°C -55°C to +125°C MIL-PRF-38534 Internal Visual 2017 Temperature Cycle 1010 Cond C Cond C 500g Constant Acceleration 2001 3000g PIND 2020 Cond A Burn-In 1015 320 hrs@125°C Interim Electical @ 160 hrs 160 hrs@125°C ( 2 x 160 hrs ) Final Electrical ( Group A ) MIL-PRF-38534 -55°C, +25°C, -55°C, +25°C, Read & Record Data & Specification +125°C +125°C PDA ( 25°C, interim to final ) 2% Radiographic Inspection 2012 Seal, Fine and Gross 1014 External Visual 2009 Cond A, C Cond A, C International Rectifier currently does not have a DSCC certified Radiation Hardness Assurance Program Part Numbering ARF 461 /EM Screening Level Model (Please refer to Screening Table) No Suffix, EM Applicable Military Test Standard WORLD HEADQUARTERS: 233 Kansas St., El Segundo, California 90245, Tel: (310) 322 3331 IR SANTA CLARA: 2270 Martin Av., Santa Clara, California 95050, Tel: (408) 727-0500 Visit us at www.irf.com for sales contact information.
