RCD PCN50
Industry’s widest range of composition resistors!
High energy and voltage capability, non-inductive
Standard tolerances of 10% & 20% (5% avail.)
Type PCN resistors are manufactured from carbon and
ceramic granules into a solid bulk composition enabling
pulse capabilities unmatched by wirewound or film resistors.
Marking is alpha-numeric or color band. Flexible manufacturing process enables customized rod or disk sizes up to 5”
diameter and 18” long. Typical applications include snubber
circuits, lightning surge, grounding resistors, RFI suppression, dummy loads, etc. Depending on the application, PCN
resistors can often satisfy requirements of UL217, 268, 294,
497A, 508, 913, 943, 991, 1459, & 1971; IEEE587, C37.90, &
Bellcore TR357 & 1089; EN61000-4, 60601, & 50082.
OPTIONS
Option HC: special coating for oil immersion (+175°C max)
Option 37: Group A screening per Mil-R-39008
Custom rod and disk sizes, expanded resistance range,
custom metallization, increased voltage/dielectric/joule
ratings avail. End caps, lug terminals, & mounting clips avail.

Max. continuous voltage is determined by E= (PR)1/2, E not to exceed the Max.Working Voltage. 2 Peak pulse voltage is dependent on resistance and pulse waveform. Levels listed are based on 10X160 nS
pulse, 10KΩ. Increased voltage available. Consult factory on each application. 3 Joule rating is dependent on resis.value, pulse duration, and repetition rate. Levels listed are based on 10mS pulse width X
20,000 cycles, 150Ω, full cooling between pulses. Increased joule ratings available. Consult factory on each application. 4 Expanded resistance range available.
