Through-hole resisT ors Professional Type Metal Film r esistors Miniature style MF0 series FeATures Power Rating 0.4W, 0.6W Resistance Tolerance 0.5%, 1%, 2%, 5%, T.C.R. 50ppm/C, 100ppm/C DerATiNg Cur Ve For resistors operated in ambient temperatures above 70C, power rating must be derated iNTroDuCTioN in accordance with the curve below. The MF0 Series Metal Film Professional 70 155 C Rated Load (%) 100 Resistors are manufactured using a vacuum 80 sputtering system to deposit multiple layers of mixed metal alloys and passivative materials 60 onto a carefully treated high grade ceramic 40 substrate. After a helical groove has been cut 20 in the resistive layer, tinned connecting leads of Ambient Temperature (C) 20 40 60 80 100 120 140 160 electrolytic copper are welded to the end-caps. The resistors are coated with layers of blue color lacquer.
