RCR Series are made by metal glaze coating on the surface of a cylindrical substrate with excellent characteristics and stable at even high resistance range.
Token offers competitive prices and are widely used in the power source protector like fluorescent's inverter, and starting resistor for Mercury Lamp. For high value resistance application, are widely used in computer and electronics, like protector of eliminate electrostatic and thunder lightning.
