Class 130 Polyurethane Round Copper Magnet Wire for Solderable Applications

Class 130 polyurethane film-insulated round copper magnet wire is a specialized type of wire. Its construction features a copper conductor coated with a polyurethane insulation that has solderable properties. This wire is ideal for situations where direct soldering is required without prior stripping.
