Through-hole resistors Cement Resistors Vertical Lead Type Normal Style [ SQM Series ] Non-Inductive Style [ NSM Series ] FEATURES Power Rating 2W, 3W, 5W, 7W, 10W Resistance Tolerance Wirewound: ±1% ±5%, Film:±5/°C T.C.R. Wirewound: ±100ppm/°C , ±300ppm/°C, Film:±300ppm/°C DERATING CURVE 40 70 (%) 155 275 °C 100 Temperature Rise The SQM Series are ceramic housed resistors with fiberglass based wirewound or ceramic rod wirewound or metal oxide core. The NSM Series are ceramic housed low-inductive resistors with ceramic rod wirewound core. Rated Load INTRODUCTION TEMPERATURE RISE 3W-5W 7W-10W 80 2W 60 40 20 -50 The materials used and the construction techniques ensure excellent flame resistance, arc resistance and moisture resistance as well as self-extinguishing capabilities. They will withstand the most rigorous loading test.
