Wirewound Resistor is a resistor made from a coil of wire that is a poor conductor. The wire is usually wound around a cylindrical form; some components use toroidal forms. The resistance is determined by how well the wire metal conducts, by its diameter (gauge), and by its length. This type of resistor can be manufactured to precision tolerance. If the wire gauge is heavy, it can dissipate large amounts of power. The component has inductive reactance, making it unsuitable for use at radio frequencies.
