Through-hole resisT ors Precision Type Metal Film r esistors Normal & Miniature style MFP series FeATures Power Rating 1/6W, 1/4W, 0.4W, 1/2W, 0.6W, 1W, 2W, 3W Resistance Tolerance 0.1%, 0.25%, (0.02%, 0.05% on request) T.C.R. 15ppm/C, 25ppm/C, (5ppm/C, 10ppm/C on request) DerATiNg Cur Ve For resistors operated in ambient temperatures above 70C, power rating must be derated iNTroDuCTioN in accordance with the curve below. The MFP Series Metal Film Precision Resistors 70 155 C Rated Load (%) 100 are manufactured using a vacuum sputtering system to deposit multiple layers of mixed metal 80 alloys and passivative materials onto a carefully 60 treated high grade ceramic substrate. After a 40 helical groove has been cut in the resistive layer, 20 tinned connecting leads of electrolytic copper are welded to the end-caps. The resistors are 20 40 60 80 100 120 140 160 Ambient Temperature (C) coated with layers of blue color lacquer. Ultra high precision resistors, ultra high stability, ultra low temperature coefficient.
