2UEW155 0.28mm Copper Enameled Winding Wire For Transformer/ Motor
0.28mm enameled wire is usually suitable for high frequency
transformer windings. Due to its small diameter and good insulation
properties, this enameled wire is ideally suited for use in the
manufacture of high-frequency transformers. In high-frequency
circuits, the insulating layer of enameled wire can effectively
reduce current loss and magnetic coupling loss, and improve the
efficiency and performance of the transformer.
Therefore, 0.28mm enameled wire can achieve better electrical
characteristics and stability in high-frequency transformer
windings, and is suitable for applications in various
high-frequency electronic equipment and communication equipment.
