Through-hole resistors Professional & Flame-Proof Type Metal Film Resistors Miniature Style [ FM0 Series ] FEATURES INTRODUCTION Power Rating 0.4W, 0.6W Resistance Tolerance ±1%, ±5% T.C.R. ±50ppm/°C, ±100ppm/°C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 DERATING CURVE The FM0 Series Metal Film Professional & Flame-Proof Resistors are manufactured using a vacuum sputtering system to deposit multiple layers of mixed metal alloys and passivative materials onto a carefully treated high grade ceramic substrate. After a helical groove has been cut in the resistive layer, tinned connecting leads of electrolytic copper are welded to the end-caps. The resistors are coated with layers of light green color lacquer. For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance with the curve below. 70 Rated Load (%) 155 °C 100 80 60 40 20 20 40 60 80 Ambient Temperature (°C) 100 120 140 160 DIMENSIONS Unit: mm ød H L øD STYLE DIMENSION Miniature L øD H ød FM0204 3.4±0.3 1.9±0.2 28±2.0 0.45±0.05 FM0207 6.3±0.5 2.4±0.2 28±2.0 0.55±0.05 13 Note: ELECTRICAL CHARACTERISTICS STYLE FM0204 FM0207 Power Rating at 70°C 0.4W 0.6W Maximum Working Voltage 200V 300V Maximum Overload Voltage 400V 600V Voltage Proof on Insulation 300V 500V Resistance Range 1Ω - 4M7Ω & 0Ω for E24 & E96 series value Operating Temp.
