RCD's PR Series Pulse Resistant resistors are designed to replace carbon composition (CC) styles in numerous applications. The PR Series feature a core composition of ceramic and heavy duty wound element. The construction enables surge performance similar to or better than carbon composition resistors (depending on resistance value) and significantly better than conventional film and wirewound resistors.Elements are protected by flameproof silicone coating for excellent environmental performance and 500V minimum dielectric strength. Series PR resistors are cost effective in a wide variety of pulse applications including telecom line feed resistors which must withstand lightning surges, snubber circuits, in-rush currents, capacitor charge/discharge circuits, etc.
