Excellent Low Cost Replacement for Composition Resistors
Series PR pulse resistors withstand higher energy pulses than
conventional film & wirewound types, without the performance disadvan-
tages of carbon comp resistors. The heavy duty construction features a
high thermal conductivity core core and coating, enabling improved
thermal transfer, long term stability, and environmental performance.
Series PR satisy a wide variety of pulse applications including lightning,
snubber, in-rush current, capacitor charge, 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 (refer to 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,
