FeATures • Welded construction • Inorganic and non-hygroscopic, Centohm coating seals and protects the resistance wire. • Exceeds MIL-R-26 moisture requirements • Centohm Resistors are designed to meet and exceed performance characteristics of vitreous enamel resistors. • Centohm is more cost effective than vitreous enamel. • ±5% resistance tolerance Ohmite’s Axiohm resistors are Centohm coated for maximum reliability. These all-welded units are characterized by their low temperature coefficients and resistance to thermal shock, making them ideal for a wide range of electrical and electronic applications.
