The WWS series wire wound resistors are manufactured using high quality resistance wires wound on ceramic substrates. The resistors are coated using layers of Flame Proof Epoxy with axial lead wire. In WWS series, 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 WMG Series Metal Glaze Resistors are manufactured with the latest sintering process to get the most stable thick metal glaze film. The resistors are insulated with light blue lacquer. WMG series offers a wide range of power rating (0.25W, 0.50W, 1W & 2W) in tolerance ±1% and ±5% with TCR less than 100 ppm/ºC

The WCSB/WCST/WCSV low ohm current sensing resistors are manufactured with high purity Ni-Cr/Cu-Ni element. These are ceramic encased resistors. WATTS offers these resistors ranging from 2mΩ to 50mΩ, having power rating from 2W to 10W.

• WCSB is axial type ceramic boat encased resistor.
• WCSV is vertical type ceramic boat encased resistor.
• WCST is axial type ceramic tube encased resistor.

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.
