Carbon Film Resistors
The CFR Series Carbon Film Resistors are made by applying a uniform layer of pure carbon onto high-quality ceramic rods. After cutting a helical groove in the resistive layer, tinned electrolytic copper leads are welded to the end caps. The resistors are finished with a tan lacquer coating. They are designed for operation in ambient temperatures up to 70°C.
