HM SERIES

SPECIFICATIONS

HERMETIC SEALED

PRECISION METAL FILM RESISTORS

PERFORMANCE CHARACTERISTICS*

* Tested in accordance with MIL-PRF-55182 at applicable MIL power ratings.

** TC is measured +25 to +85°C, expanded range available

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.
