The PSP Series Resistors are wound on 70 350 C Rated Load (%) 100 Fiberglass core. The materials used and the 80 construction techniques ensure excellent flame resistance, arc resistance and moisture 60 resistance as well as self-extinguishing 40 capabilities. They will withstand the most 20 rigorous loading test. 0 Ambient Temperature (C) -50 0 50 100 150 200 250 300 350 As resistors in radio and television receivers, hazardous conditions such as smoking and redheat can be completely prevented by the proper choice of power resistors.
