Pulse tolerant surface mount resistors!
Series PRM withstand high energy pulses, and are superior to
conventional film & wirewound types. The heavy duty construction
features a ceramic core, enabling improved thermal transfer and long
term stability. Elements are protected by flame-retardant molding for
excellent environmental performance. Alpha-numeric marking is
standard. PRM resistors are cost effective in a wide variety of pulse
applications including telecom line feed resistors, snubber circuits, in-
rush currents, capacitor charge/discharge circuits, lightning surges, etc.

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. 30% safety factor is recommended for infrequent pulses, 50%
typ. for repetitive pulses (request Note R42 for derating factors attributable 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,
