Melf Carbon Film Resistors
iNtRodUCtioN
The MCF Series Melf Carbon Film 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.
SMD enabled structure. The resistors are
coated with layers of lacquer.
