Wire Wound Resistor Manufacturers

Wire wound resistor series is one of the more commonly used resistors. The resistor body of wire wound resistor is resistance wire. The resistance wire is wound around the ceramic skeleton, the leads are connected, and the surface is coated with a layer of glass glaze or insulating paint. 

Wire wound resistors are a type of resistor wound from a constantan, manganese-copper, or nickel-alloyed alloy wire on a ceramic skeleton, with a protective paint or glass glaze on the surface.

The performance characteristics of wire wound resistor series extremely low noise, high temperature resistance, high power, good stability, small temperature coefficient, high precision, but poor high frequency characteristics. The resistance range of wire wound resistor series is usually 0.1Ω ~ 5MΩ, especially suitable for high temperature and high power occasions.
