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.
