ROP Vishay Sfernice Power Metal Oxide Film Resistors FEATURES * 2W and 4W at 25C * NF C 83-210 * Good overload performance * High reliability level * Small size The "ROP" resistors combine low price with outstanding performance and are therefore suitable for both professional and general purpose applications. These power metal oxide film resistors can favorably be used as a substitute for general purpose cemented or lacquered wirewound resistors, in medium and high ohmic values ranges. * High electrical insulation * Resistance to cleaning solvents * Excellent climatic performances * Good mechanical strength DIMENSIONS in millimeters 25 min. 25 min.
