Customized components are an RCD speciality!
RCD’s PMF Series meets the need for ultra-precision performance
when product reliability is a must. Stability levels (comparable
to those of precision wirewound resistors), coupled with the
excellent high-frequency performance of film resistors, makes
the PMF Series the universal choice. State-of-the-art deposition
and trim equipment enables the industry’s widest resistance
range. The exceptional performance of this series provides new
opportunities for circuit designers to obtain the utmost in long
term reliability without the need for post circuit trimming.

MATCHED SETS AND NETWORKS
P/N DESIGNATION:
RCD’s experience in matching resistors for sets and
networks can result in an economical solution for many
circuits. Cost savings up to 50% can be achieved by allowing
relatively loose absolute tolerances but tight matching
requirements by pair or set. Resistance matching is
available to 0.01% and T.C. tracking to ±1ppm/°C.
