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.

THICK FILM CHIP RESISTORS
The CR series Thick Film Chip Resistors are manufactured by screening a metal glaze layer on a high grade ceramic body. The different resistance values are obtained by using different compositions of metal glaze. The end contacts are made to ensure optimum solderability. The resistive layer is then given a protective coating.
The CR series offer a wide range of power ratings from 1/20W to IW and are available in tolerance ranges of ± 1 % and ±5% % with insulation Resistance ≥ 1000MΩ. .Miniature size, excellent mechanical strength and electrical stability ensures reduced costs and enhances dependability.
ZERO OHM RESISTOR / JUMPER WIRE
The WC12/WC25/WM12/WM25 zero ohm resistors are manufactured to give extremely low resistance value. A single black band indicates that the resistor is Zero ohm. The WJ jumper wires are manufactured using high grade tin plated electrolytic copper wire. This is provided in taped form having 5mm pitch.
WIRE WOUND RESISTORS – NON INDUCTIVE
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.
