Nicrom film deposited on 96% alumina ceramic. . Laser machine is used to achieve the highly precise resistance tolerance by cutting a helical groove in the film layer. Tin coated electrolytic copper wire are soldered to the center of the termination. The resistor are molded with powder epoxy for electrical , mechanical and climatic protection, Marking is applied with respect to designated value on coated Resistor. All Resistors are subjected to tesing before final taping process.
