RCD's PRM Series Pulse Resistant resistors are de-
signed to replace carbon composition styles in numerous
applications. The PRM Series feature a core composi-
tion 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 improved environmen-
tal stability (see comparison chart). Elements are
protected by high-temp molded case for excellent envi-
ronmental performance and 500V minimum dielectric
strength. PRM 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 charging and
discharge circuits, etc.
