The materials used and the construction
techniques ensure excellent flame resistance,
arc resistance and moisture resistance as well
as self-extinguishing capabilities. They will
withstand the most rigorous loading test.
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.
