MPT Power Your Critical Mission Today Models Available Input: 28 V nominal 10 A output Qualified to MIL-PRF-38534 Class H and Class K 1.0 DESCRIPTION The SVRME is specifically designed for use with the SVR Series of DC-DC converters in the harsh radiation environment of space applications. The SVRME design is fully passive, giving a strong resistance to radiation degradation, and is designed in accordance with Aerospace TOR requirements. Product performance is guaranteed through extensive circuit worst-case analysis. The SVRME Series of EMI filters is suited for use in low Earth orbit (LEO), medium Earth orbit (MEO), geostationary orbit (GEO), deep space, and launch vehicle programs. 1.1 FEATURES • Up to 10 A maximum current • High reliability • Wide input voltage range: 0 to 40 V • High input transient voltage: 50 V for 1 second • 40 dB minimum attenuation at 500 kHz • Continuous operation over full military temperature range of -55 °C to +125 °C with no power derating • One module filters the emissions of multiple SVR Series DC-DC converters 1.2 SPACE LEVEL CHARACTERIZATIONS • Fully passive design is immune to degradation from radiation • Worst-case analysis, stress, radiation, reliability reports available 1.3 MANUFACTURING AND COMPLIANCE • Qualified to MIL-PRF-38534 Class H and Class K, DLA Drawing # 13009 • Available compliant to MIL-HDBK-1547 and Aerospace TOR component level element evaluation • MIL-PRF-38534 element evaluated components • MIL-STD-461C/D/E/F requirements for conducted emissions • Manufactured in a MIL-PRF-38534 Class H and Class K facility • MIL-STD-883 • ISO-9001 1.4 PACKAGING • Low-profile: 3.005” x 1.505” x 0.400” • Max weight: 91 g • Industry standard pinout • Precision seam-welded hermetic metal case 1.5 SIMILAR PRODUCTS AND ACCESSORIES • DVME 15 A EMI filter for military/avionics applications • Custom versions available • SVR Series DC-DC converters Products and reports described in this datasheet are subject to all export license restrictions and regulations which may include but are not limited to ITAR (International Traffic in Arms Regulations) and the Export Administration and Foreign Assets Control Regulations.
