• The materials used and the construction techniques ensure excellent flame resistance, arc
resistance and moisture resistances as well as selfextinguishing capabilities. They will withstand the
most rigorous loading test.
• As resistors in radio and television receivers, the
hazardous conditions of smoking and redheat can
be completely prevented by the proper choice of
power resistors.
