The FC0 Series Carbon Film Professional &
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 green color lacquer.
