leaded resISTORS High Power Type Metal Film Resistors Ultra Miniature Style [ FMP Series ] FEATURES Power Rating 1/2W, 1W, 2W, 3W,4W Resistance Tolerance ±1%, ±5% T.C.R. ±100ppm/°C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 INTRODUCTION DERATING CURVE The FMP Series Metal Film High Power Resistors are manufactured using a vacuum sputtering system to deposit multiple layers of mixed metal alloys and passivative materials onto a carefully treated high grade ceramic substrate. After a helical groove has been cut in the resistive layer, tinned connecting leads of electrolytic copper are welded to the end-caps. The resistors are coated with layers of pink color lacquer. For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance with the curve below.
