leaded resISTORS Melf Metal Film Resistors MMP Type High Power Style [ MMP Series ] FEATURES Power Rating 1W, 2W Resistance Tolerance 1%, 2%, 5% T.C.R. 50ppm/C, 100ppm/C, 200ppm/C DERATING CURVE For resistors operated in ambient temperatures above 70C, power rating must be derated in accordance with the curve below. INTRODUCTION The MMP Series Melf Metal Film High Powe Resistors are manufactured using vacuum sputtering system to deposit multiple layers of mixed metals alloy and passivative materials onto a carefully treated high grade ceramic substrate. After a helical groove has been cut in the resistive layer, SMD enabled structure and high power in small packages. The resistors are coated with layers of blue color lacquer.
