Carbon Film Resistors

Flame-Proof Type

Normal & Miniature Style [ FCR Series ]

INTRODUCTION

The FCR Series Carbon Film Flame-Proof

Resistors are manufactured by coating a

homogeneous film of pure carbon on high

grade ceramic rods. 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 gray color lacquer.
