Wire Wound Resistors

Wire Wound Resistors VALUES RANGING FROM 0.01E TO 100K WWR
Wirewound resistors are commonly made by winding a metal wire, usually nichrome, around a ceramic, plastic, or fiberglass core. The ends of the wire are soldered or welded to two caps or rings, attached to the ends of the core. The assembly is protected with a layer of paint, molded plastic, or an enamel
