Through-hole resistors General Type Metal Film Resistors Normal & Miniature Style [ MFR Series ] FEATURES Power Rating 1/6W, 1/4W, 1/2W, 1W, 2W, 3W Resistance Tolerance ±0.5%, ±1%, ±5% T.C.R. ±15ppm/°C, ±25ppm/°C, ±50ppm/°C, ±100ppm/°C DERATING CURVE For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance with the curve below. INTRODUCTION The MFR Series Metal Film 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 blue color lacquer.
