PD-94596A AME270461 SERIES EMI FILTER HYBRID / HIGH RELIABILITY Description The AME Series of EMI filters have been designed to provide full compliance with the input line reflected ripple current requirement specified by CE03 of MILSTD-461C over the full military temperature range while operating in conjunction with the corresponding AFL series of DC/DC converters. These filters are offered as part of a complete family of conversion products providing single and dual output voltages while operating from nominal +270 input line voltage. Other converters operating with a similar switching frequency will also benefit by use of this device. AME Features n n n n n n These EMI filters are hermetically packaged in two enclosure variations, utilizing copper-core pins to minimize resistive DC losses. Three lead styles are available, each fabricated with Advanced Analog’s rugged ceramic lead-to-package seal assuring long term hermetic seal integrity in harsh environments. Up to 1.5 Ampere Output Current Attenuation > 35dB @ 200 KHz Low Profile (0.38”) Seam Welded Package Ceramic Feedthru Copper-Core Pins Operation Over Full Military Temp. Range Standard Military Drawings Available Both grades are tested to meet the complete group “A” test specification over the full military temperature range with no derating. Two grades with more limited screening are also available for use in less demanding applications. Variations in electrical, mechanical and screen requirements can be accommodated. Contact IR Sant Clara for special requirements. Manufactured in a facility fully qualified to MIL-PRF38534, these converters are available in four screening grades to satisfy a wide range of applications. The CH grade is fully compliant to the requirements of MILPRF-38534 for class H. The HB grade is fully processed and screened to the class H requirement, but does not include element evaluation to the class H requirement.

Operation above maximum ratings may cause permanent damage to the device. Operation at maximum ratings may degrade performance and affect reliability. Device can tolerate ± 720 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 AME270461 Series AME270461 Block Diagram Input 1 12 2 Output 11 20 nF 3 10 2.24 µF 1.12 µF Case 4 9 20 nF Input Return 5 8 6 7 Output Return Refer to last page for Pin Designation Circuit Operation and Application Information The AME series of filters employ three stages of filtering in a low pass configuration designed to attenuate the higher frequency components of ripple currents generated by high frequency switching DC/ DC converters. The Block Diagram describes the general arrangement of the principal elements which have been connected to provide both differential and normal mode buffering between the input and output terminals. Employing only passive elements, AME filter operation is initiated simply by insertion into the input power path between one or more DC/DC converters and their input DC voltage bus. In this connection, output pins of the filter will be connected to input pins of the converters. When a single AME filter is used in conjunction with multiple DC/DC converters, the use will be limited to the maximum output current capability specified in the AME electrical table.1 A typical connection utilizing one filter to drive two converters is illustrated on page 1. 1 To calculate the input current (i in ) requirement of any one converter, first determine the maximum output power by multiplying output voltage by maximum load current, divide this power by the efficiency to obtain input power and then divide input power by inputvoltage to obtain the input current (i in ). Note that to obtain worst case input current, you must use maximum load current, minimum efficiency and minimum line voltage in this calculation. www.irf.com 3 AME270461 Series Available Screening Levels and Process Variations for AME270461 Series Requirement MIL-STD-883 Method Temperature Range No Suffix ES Suffix HB Suffix CH Suffix -20 to +85°C -55°C to +125°C -55°C to +125°C -55°C to +125°C Element Evaluation * MIL-PRF-38534 Internal Visual 2017 Temperature Cycle Yes Yes Yes 1010 Cond B Cond C Cond C Constant Acceleration 2001 500g Cond A Cond A Burn-in 1015 48hrs@ 85°C 48hrs@ 125°C 160hrs @ 125°C 160hrs @ 125°C Final Electrical MIL-PRF-38534 25°C 25°C -55, +25, +125°C -55, +25, +125°C (Group A) & Specification Seal, Fine & Gross 1014 Cond A Cond A, C Cond A, C Cond A, C External Visual 2009 Yes Yes Yes Per Commercial Standards Available Standard Military Drawing (SMD) Cross Reference Standard Military Drawing PIN Vendor CAGE Code Vendor Similar PIN 98026-01HUA 52467 AME270461W/CH 98026-01HUC 52467 AME270461W/CH 98026-01HXA 52467 AME270461X/CH 98026-01HXC 52467 AME270461X/CH 98026-01HYA 52467 AME270461Y/CH 98026-01HYC 52467 AME270461Y/CH 98026-01HZA 52467 AME270461Z/CH 98026-01HZC 52467 AME270461Z/CH 4 www.irf.com AME270461 Series AME270461 Case Style Outlines Case X Case W Pin Variation of Case Y 3.000 ø 0.128 2.760 0.050 0.050 1 12 0.250 1.000 Ref 0.200 Typ Non-cum 6 7 1.260 1.500 0.250 1.000 Pin ø 0.040 0.220 2.500 0.220 Pin ø 0.040 2.800 2.975 max 0.525 0.238 max 0.42 0.380 Max 0.380 Max Case Y Case Z Pin Variation of Case Y 1.150 0.300 ø 0.140 0.25 typ 0.050 1 12 0.250 1.000 Ref 0.250 1.000 Ref 0.200 Typ Non-cum 6 7 1.500 1.750 2.00 1.750 0.050 Pin ø 0.040 0.375 0.220 2.500 0.36 2.975 max 2.800 0.238 max 0.525 0.380 Max Tolerances, unless otherwise specified: www.irf.com Pin ø 0.040 0.220 0.380 Max .XX .XXX = = ±0.010 ±0.005 5 AME270461 Series Pin Designation Pin No. Designation 1 Positive Input 2 Positive Input 3 Positive Input 4 Input Return 5 Input Return 6 Input Return 7 Output Return 8 Output Return 9 Output Return 10 Positive Output 11 Positive Output 12 Positive Output Part Numbering AME 270 461 X / CH Model Screening — Input Voltage 28 = 28V 50 = 50V 270 = 270V , ES, HB, CH Case Style W, X, Y, Z Applicable Military Test Standard 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.
