FKN2WS Wirewound Resistors

Wirewound Resistors Through-hole resistors Fusible & Flame-Proof Type Normal & Miniature Style [ FKN Series ] 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.
