The WWHS series wire wound high surge immune resistors are manufactured using high quality resistance wires wound on ceramic substrates. The resistors are coated using layers of Flame Proof Silicon Epoxy with axial lead wires. These resistors have high surge voltage immunity. In WWHS series, for resistors up to 5W, the resistance value is color coded with 3 bands plus a tolerance band. An additional black band indicates that the resistor is wire wound. For resistors 6W and above, the value is printed on the resistor.

The WMO series Metal Oxide Film Resistors are manufactured using the latest technology to ensure a very stable resistive medium. The resistors are insulated with layers of flame proof epoxy. The WMO series offer a wide range of power rating (0.25W, 0.50W, 1W, 2W & 3W) having tolerance ranges of ±1 % & ±5 %

The WWF series wire wound fusible resistors are manufactured to perform as a regular resistor under normal conditions and as a fuse under excessive load. In WWF series, resistors up to 5W, the resistance value is colour 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.
