The WCF Series Carbon Film Resistors are manufactured using mechanised high vacuum carbonising plants. This ensures a stable resistive film. The resistors are insulated with layers of light brown lacquer. The WCF series offer a wide range of power ratings (0.125 W, 0.25W, 0.4W, 0.5W, 1W, 2W & 3W) with a tolerance of ± 5%. and TCR ±1000 ppm/ºC.

The WWFHS series wire wound fusible high surge immune resistors are manufactured to perform as a regular resistor under normal conditions and as a fuse under excessive load. These fusible resistors have high surge voltage immunity. In WWFHS series, for resistors up to 5W, the resistance value is color coded with 3 bands plus a tolerance band. An additional white band indicates that the resistor is fusible. For resistors 6W and above, the value is printed on the resistor.

The WWN series wire wound resistors - non inductive have very low inductance (less than 1µH), high heat dissipation and low TCR. The resistors are coated using layers of Flame Proof Epoxy with axial lead wire. In WWN series, resistors up to 5W, the resistance value is color coded with 3 bands plus a tolerance band. An additional yellow band indicates that the resistor is Non Inductive. For resistors 6W and above, the value is printed on the resistor.
