Wirewound resistor » Resistor Guide

What is a wire-wound resistor? A wire wound resistor is an electrical passive component that limits current. The resistive element exists out of an insulated metallic wire that is winded around a core of non-conductive material. The wire material has a high resistivity, and is usually made of an alloy such as Nickel-chromium (Nichrome) or a copper-nickel-manganese alloy called Manganin.

Gore''s Technologies | About ePTFE | Gore

Expanded polytetrafluoroethylene, or ePTFE, is the core material in many of Gore’s solutions. An ePTFE merane is created when PTFE — a linear polymer consisting of fluorine and carbon molecules — is expanded, creating a microporous structure with very desirable characteristics, including a high strength-to-weight ratio, biocompatibility, high thermal resistance and many others:

Buy Silver from Surepure Chemetals

Surepure Chemetals sells silver wire ranging from 0.001" small diameter wire (smaller than a human hair) up to 1" or larger diameter straight length rods. We use the term "wire" for smaller diameters that are supplied on a spool or as a coil. We use the term "rod" when the diameter is large enough that it can be supplied as a straight length.
