RCD Series HM hermetically sealed precision metal film resistors are designed for demanding applications including high humidity, salt atmosphere, and other hostile environments. 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 temperature coefficients exceeds the military range of MIL-PRF-55182, enabling new opportunities for circuit designers.
