APPLICATION NOTE
chart above select model meet desired surge level. Pulse exceed peak ratings (derate Opt.X), average power during repetitive pulses rated safety factor recommended infrequent pulses, typ. repetitive pulses (request Note derating factors attributable pulse width, rep. rate, temp., altitude, humidity). Verify evaluating under worst-case conditions. Depending specifics, series often satisfy surge requirements UL-217, -268, -294, -497, -508, -913, -943, -991, -1459, -1971, ANSI/IEEE C62.41, CCITT (Rec.
