Cost effective high-voltage surge resistors to 200 joules
Available on RCD’s exclusive SWIFTTM program
Molded surface mount version available (PRM series)
Excellent Low Cost Replacement for Composition Resistors
Series PR pulse resistors withstand higher energy pulses than conven-
tional film & wirewound types, without the performance disadvantages
of carbon comp resistors. The heavy duty construction features a high
thermal conductivity core and coating, enabling improved stability and
environmental performance. Series PR satisy a wide variety of pulse
applications including lightning, snubber, in-rush current, capacitor
charge, etc. RoHS (Sn) or Mil-spec (Sn-Pb) termination finish available.

APPLICATION NOTE
Use chart above to select model to meet desired surge level. Pulse not to exceed
peak V & j ratings (derate 30% for Opt.X), and average power during repetitive
pulses nte rated W. A safety factor of 30% typ. is recommended for infrequent
pulses, 50% typ. for repetitive pulses (refer to Note R42 for derating factors at-
tributable to pulse width, rep. rate, temp., altitude, humidity). Verify by evaluating
under worst-case conditions. Depending on specifics, PR series can often satisfy
the surge requirements of UL-217, -268, -294, -497, -508, -913, -943, -991, -1459,
-1971, ANSI/IEEE C62.41, CCITT (Rec. K17), Bellcore TR-NWT-001089 & TR-
