These all-welded units are characterized by their low temperature coef- ficients and resistance to thermal shock, making them ideal for a wide range of electrical and electronic applications. F eAt u r e s

  • Welded construction
  • Inorganic and non-hygroscopic, Centohm coating seals and protects the resistance wire.
  • Exceeds MIL-R-26 moisture require- ments
  • Centohm Resistors are designed to meet and exceed performance charac- teristics of vitreous enamel resistors.
  • Centohm is more cost effective than vitreous enamel.
  • ±5% resistance tolerance OptiOns Noninductive: This specially designed version is wound using the Ayrton-Perry method. Resistance Tolerances: Options include 5%, 1%, 0.5%, 0.25%, and 0.1% resistors. Terminal Sizes: Alternate terminal diameters available. Tape and Reel: Resistors taped for automatic insertion.
