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,

ANSI/IEEE C62.41, CCITT (Rec. K17), Bellcore TR-NWT-001089 & TR-TSY-000057,
