DESCRIPTIONThe SFCS-461TM Series EMIdesigned to reduce the reflected input ripple current of high frequency DC/DC converters. SFCS28-461 filters minimize elec-tromagnetic interference (EMI) for Interpoints space application converters. These filters are intended for use in 28 volt applica-tions which must meet MIL-STD-461 levels of conducted emis-sions. One filter can be used with multiple converters up to the rated throughput current of the filter.SCREENINGThe SFCS28-461 filter offers three screening options - Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of - (O) or H, per MIL-STD-38534. Interpoint model numbers use an O in the RHA designator position to indicate the - (dash) Radiation Hardness Assurance level of MIL-PRF-38534, which is defined as no RHA. See Class H and K, MIL-PRF-38534 Screening tables for more information. INPUT RIPPLE AND ESwitching DC/DC converters naturally generate two noise components on the power in FEATURES Fully qualified to Class H or K Passive components used for maximum tolerance in space environments Nominal 28 V input, 0 V to 50 V operation Up to 5 A throughput current 70 dB attenuation typical at 500KHz Compatible with MIL-STD-704 A-E 28 VDC power busINPUT VOLTAGE AND CURRENTModelSFCS28-461Current (A)5 Crane Aerospace & Electronics Power SolutionsSEICrane Aerospace & ElectronicsElectronics Group (Interpoint Brand)PO Box 97005 Redmond WA 98073-9705425.882.3100 electronics@craneae.comPage 1Rev B - 2007040428 VOLT INPUT - 5 APositiveInputInputCommonPositiveOutputOutputCommonSFCS28-46117 H17 H17 H6 F50 V6 F50 V6 F50 V.015 F 500 V.015 F 500 V.015 F 500 V.015 F 500 V100 H100 H3.2 FI 1: SCOPERATING CCIR 0 to 50 VDC continuous for 28 V modelsLST 300 CSTRCOTDOPI 100 megohm minimum at 500 VDC Any pin to caseMES 3.005 x 1.505 x 0.400 inches (76.33 x 38.23 x 10.16 mm) See case U for dimensions.Weight (maximum) 110 grams maximumS Space Prototype (O), Class H, or Class K Radiation toler specifications without notice.Copyrigh
