UL Certificated High Quality 39WG NEMA Copper Enameled Wire
Enameled copper wire is an important component in the production of microelectronic products because of its fine wire diameter, high temperature resistance, good insulation performance, and excellent conductivity. Its versatility and reliability make it the first choice for manufacturers of small electronic equipment.
As the demand for smaller, more powerful electronics continues to grow, enamelled copper wire will undoubtedly remain a staple in microelectronics.
