Industry’s widest range!
Tolerances to ±0.01%, TC’s to ±5ppm!
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
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.
