Through-hole resistors Metal Oxide Film Resistors Flame-Proof Type Normal & Miniature Style [ RSF Series ] FEATURES Power Rating 1/4W, 1/2W, 1W, 2W, 3W, 5W Resistance Tolerance ±2%, ±5% T.C.R. ±300ppm/°C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 INTRODUCTION The RSF Series Metal Oxide Film Flame-Proof Resistors offer excellent performance in applications where stability and uniformity of characteristics are desired. They provide lower cost alternatives to Carbon Composition Resistors and General Purpose Metal Films. Metal Oxides also can replace many low power General Purpose wirewound applications, saving both money and time, with shorter delivery cycles. The normal style & ‘RSF-WV’ style of RSF series are coated with layers of gray flameproof lacquer, and the miniature style except ‘RSF-WV’ style are coated with layers of pink colors flame-proof lacquer. DERATING CURVE For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance with the curve below. 70 Rated Load (%) 155 235°C 100 80 60 40 20 50 100 150 200 250 Ambient Temperature (°C) DIMENSIONS Unit: mm STYLE ød H L øD Note: RSF1WS (for MB Type) ød = 0.8±0.05mm RSF3WV, RSF4WV: Marking Printed DIMENSION Normal Miniature L øD H ød RSF-25 RSF50S / RSF1WV 6.3±0.5 2.4±0.2 28±2.0 0.55±0.05 RSF-50 RSF1WS 9.0±0.5 3.3±0.3 26±2.0 0.55±0.05 RSF100 RSF2WS / RSF2WV 11.5±1.0 4.5±0.5 35±2.0 0.8±0.05 RSF200 RSF3WS 15.5±1.0 5.0±0.5 33±2.0 0.8±0.05 - RSF3WV 16.5+0/-1.5 6.0+0/-0.5 33±2.0 0.8±0.05 RSF3WM RSF5SS 17.5±1.0 6.5±1.0 32±2.0 0.8±0.05 - RSF4WV 20+0/-1 9.0+0/-0.5 31±2.0 0.8±0.05 RSF300 RSF5WS 24.5±1.0 8.5±1.0 38±2.0 0.8±0.05 RSF500 - 24.5±1.0 8.5±1.0 38±2.0 0.8±0.05 21 ELECTRICAL CHARACTERISTICS Normal STYLE STYLE RSF-25 RSF-50 RSF100 RSF200 RSF3WM RSF300 RSF500 Power Rating at 70°C 1/4W 1/2W 1W 2W 3W Maximum Working Voltage 200V 250V 350V 450V 500V 750V Maximum Overload Voltage 300V 400V 600V 700V 800V 1,000V Voltage Proof on Insulation 250V 350V 500V Resistance Range 1Ω - 1MΩ & 0Ω for E24 series value Operating Temp.
