RSO www.vishay.com Vishay Sfernice Wirewound Resistor, Industrial High Power, Enamelled Corrugated Tape, Tubular FEATURES 160 W to 1 kW at 25 C Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 The remarkable dissipation power of this series is the result of an original winding method using corrugated edge-wound tape, thus forming a very active radiator. The enameling follows the contour of the resistive element and provides effective insulation and support for the winding. The tubular core is of special ceramic, capable of withstanding high thermal shock and overload of short duration.
