leaded resISTORS Flame-Proof Type Metal Film Resistors High Power Style [ FMP Series ] FEATURES Power Rating 1/2W, 1W, 2W, 3W Resistance Tolerance 1%, 5% T.C.R. 100ppm/C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 DERATING CURVE INTRODUCTION The FMP Series Metal Film Power Flame Proof 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, tinned connecting leads of electrolytic copper are welded to the endcaps. The resistors are coated with layers of pink color lacquer. For resistors operated in ambient temperatures above 70C , power rating must be derated in accordance with the curve below. 70C Rated Load (%) 100 80 60 40 20 20 40 60 80 100 120 140 160 180 Ambient Temperature (C) DIMENSIONS Unit : mm STYLE od H L oD DIMENSION Ultra Miniature L oD H od FMP-50 3.40.3 1.90.2 282.0 0.450.05 FMP100 6.30.5 2.40.2 282.0 0.550.05 FMP200 9.00.5 3.90.3 262.0 0.550.05 FMP300 15.51.0 5.00.5 332.0 0.80.05 15 Note : ELECTRICAL CHARACTERISTICS STYLE FMP-50 FMP100 FMP200 FMP300 Power Rating at 70 C 1/2W 1W 2W 3W Maximum Working Voltage 200V 350V 500V 750V Maximum Overload Voltage 400V 600V 700V 1000V Dielectric Withstanding Voltage 300V 500V Resistance Range 1 ~ 10M & 0 for E24 & E96 series value Operating Temp.
