SURGE RESISTORS, 1/8W to 15W, 2KV to 25KV PR SERIES RoHS Term."W" is Pb-free and RoHS compliant; "Q" is Sn-Pb Excellent Low Cost Replacement for Composition Resistors Series PR pulse resistors withstand higher energy pulses than conventional 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. Cost effective high-voltage surge resistors to 200 joules Available on RCD's exclusive SWIFTTM program Molded surface mount version available (PRM series) OPTIONS Opt.
