The Vishay Dale MIL-PRF-18546 Qualified Wirewound Resistors have a complete welded and molded construction for total environmental protection. These resistors mount directly onto a chassis to utilize heat-sink effect. This range of wirewound resistors offers high stability at conventional power ratings and flat marking surface for easy identification. Features: -? Molded construction for total environmental protection -? Resistance Tolerance 1% -? High-temperature silicone coating or encapsulate -? Complete welded construction -? Meets applicable requirements of MIL-PRF-18546 -? Available in non-inductive styles (type NH) with Ayrton-Perry winding for lowest reactive components -? Mounts on chassis to utilize heat-sink effect -? Excellent stability in operation (< 1 % change in resistance) Applications: -?DC/DC converters -?AC/DC inverters -?High-voltage bleeders -?Dynamic braking -?Bias supply -?Motor speed controls -?Voltage divider networks -?Filament dropping -?Capacitor charging/discharging regulation -?Voltage dropping -?Electrical loads -?Crow-bar circuits -?Current shunts
