Through-hole resistors Fusible & Flame-Proof Type Wirewound Resistors Normal & Miniature Style [ FKN Series ] FEATURES Power Rating 1/2W, 1W, 2W, 3W, 4W, 5W, 7W Resistance Tolerance ±1%, ±5% T.C.R. ±350ppm/°C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 DERATING CURVE INTRODUCTION The resistor element is a resistive wire which is wound in a single layer on a ceramic rod, with tinned connecting wires of electrolytic copper welded to the end-caps. The ends of the resistive wire are connected to the caps by welding. The resistors are coated with layers of green color flame-proof lacquer. Overload protection without risk of fire. Wide range of overload currents. For resistors operated in ambient temperatures above 40°C, power rating must be derated in accordance with the curve below.
