Carbon Film Resistors - CF Series
Carbon Film Resistors - CF Series
CF Series are the earliest and a still popular type made by
breaking down hydrocarbon gases at high temperature in a vacuum
to form a carbonic deposit on the surface of a cylindrical substrate.
Trimming to value is accomplished by the cutting of spiral grooves.
The material is painted on the substrate in
a spiral pattern and cured at a moderately elevated temperature.
Token offers competitive prices and widely used in the electronics,
and consumer electrical industries.
