CARBON RESISTORS

Carbon Film Resistors

CF carbon,resistor

Carbon Film Resistors are ready in use worldwide in all types of applications. It is the earliest and still popular resistors.


Carbon thin film resistors are made by sputtering the resistive material onto the surface of the ceramic rod. Sputtering is a method used in vacuum deposition.


Tokenchina offers competitive prices and good operational characteristics carbon film Resistors which widely used in the electronics and consumer electrical industries.


Full CF Series meet RoHS compliant.
