ꢀ Industry’s widest range!
ꢀ Tolerances to ±0.01%, TC’s to ±5ppm!
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.
ꢀ Hermetic enclosure enables exceptional environmental
stability and physical protection
ꢀ Power levels are above equivalent military ratings!
ꢀ Available on exclusive SWIFTTM delivery program!
ꢀ Extremely low noise, thermal EMF, and voltage coefficient
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.
OPTIONS
ꢀ OPTION EK : Group A screening per Mil-R-10509
ꢀ OPTION EL: Group A & B screening per Mil-R-10509
ꢀ A variety of options are available including custom sizes,
formed leads, matched sets, non-standard values, special
lab testing/burn-in, increased power/voltage/pulse capability,
etc. Customized components are RCD’s specialty!
