Through-hole resisT ors Fusible & Flame-Proof Type Metal Film Resistors Normal & Miniature Style FRM Series FeATures Power Rating 1/4W, 1/2W, 1W, 2W, 3W Resistance Tolerance 2%, 5% T.C.R. 200ppm/C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 DerATiNg Cur Ve iNTroDuCTioN For resistors operated in ambient temperatures above 70C, power rating must be derated The FRM Series Metal Film Fusible & in accordance with the curve below. Flame-Proof Resistors are manufactured using 70 155 C Rated Load (%) a vacuum sputtering system to deposit multiple 100 layers of mixed metal alloys and passivative 80 materials onto a carefully treated high grade 60 ceramic substrate. After a helical groove has 40 been cut in the resistive layer, tinned connecting 20 leads of electrolytic copper are welded to the end-caps. The resistors are coated with layers Ambient Temperature (C) 20 40 60 80 100 120 140 160 of gray color lacquer for normal size & pink color lacquer for miniature size. Overload protection without risk of fire. Wide range of overload currents.
