RCD Series HM hermetically sealed precision metal film
resistors are designed for demanding applications including
high humidity, salt atmosphere, and other hostile environ-
ments. The improved environmental stability is achieved by
hermetically sealing the resistor element within the external
insulated tube.
The wide choice of resistance values, tolerances, and tempera-
ture coefficients exceeds the military range of MIL-PRF-55182,
enabling new opportunities for circuit designers.
