A homogeneous film of nicrom alloy is sputtered deposited on 85 % alumina ceramic rods and conditioned to achieve the desired temperature coefficient. Nickel plated caps are firmly pressed on the metallised rods. Laser machine is used to achieve the highly precise resistance tolerance by cutting a helical groove on the nicrom film layer. Tin & lead coated electrolytic copper wire are spot welded to the center of the termination caps. The resistor are molded with special epoxy for electrical, mechanical and climatic protection, then marked with alphanumeric stamps with respect to designated value on resistor. All resistors are subjected to screening before packing.
