A homogeneous Film of Nicrom alloy is sputtered deposited on 70 to 85% Alumina Ceramic Rods and conditioned to achieve the desired Temperature Coefficient. Nickel plated caps are fimly  pressed on the metallised rods. A special Laser machine is used to achieve the highly precise resistance tolerance by cutting a helical groove in the nicrom film  layer. Tin coated electrolytic copper wire are spot welded to the center of the termination caps. The resistor are coated with special epoxy or Flame proof Epoxy for Electrical , Mechanical and climatic protection,colour codes are applied with respect to designated value on coated Resistor.All Resistors are subjected to tesing before final taping process.
