Homogeneous film of conductive & Ruthenium oxide resistive ink is screen printed 96% alumina rods.Pre- welded tin coated electrolytic copper wire spot welded on center of the end caps are force fitted from both sides. Triming machine is used to achieve the highly precise resistance tolerance by triming . The resistor are coated with screen printed polymer coat for electrical, mechanical and climatic protection. Marking is done with respect to type, designated value,tolerance and date code on coated Resistor.
