Through-hole resistors Fiberglass Cement Resistors Power Wirewound & Axial Lead Type Normal & Miniature Style [ PSP Series ] FEATURES Power Rating 4W, 5W, 7W, 9W, 11W, 17W Resistance Tolerance ±5%, ±10% T.C.R 400±50ppm/°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 PSP Series Resistors are wound on Fiberglass core. 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. 70 Rated Load (%) 350 °C 100 80 60 40 20 0 -50 As resistors in radio and television receivers, hazardous conditions such as smoking and redheat can be completely prevented by the proper choice of power resistors. 0 50 Ambient Temperature (°C) 100 150 200 250 300 350 DIMENSIONS Unit: mm STYLE 36±3 L 36±3 W H * * ød * 6mm, reduced solderability in this area DIMENSION Normal Miniature L W H ød PSP400 - 20±1.0 6.4±0.3 6.4±0.3 0.8±0.02 PSP500 - 25±1.0 6.4±0.3 6.4±0.3 0.8±0.02 - PSP7WS 25±1.0 9.0±0.3 9.0±0.3 0.8±0.02 PSP700 - 38±1.0 6.4±0.3 6.4±0.3 0.8±0.02 PSP900 - 38±1.0 9.0±0.3 9.0±0.3 0.8±0.02 PSP11A - 50±1.5 9.0±0.3 9.0±0.3 0.8±0.02 PSP17A - 75±2.0 9.0±0.3 9.0±0.3 0.8±0.02 61 Note: ELECTRICAL CHARACTERISTICS STYLE PSP400 PSP500 PSP7WS Power Rating at 70°C 4W 5W 7W Maximum working voltage PxR Voltage Proof on Insulation 2000V Resistance Range 0.1 Ω - 9.1K Ω Operating Temp.
