0.15mm X 640 USTC Copper Litz Wire
0.15MM X 640 STRANDS USTC LITZ WIRE ENAMELED COPPER MAGNET LITZ WIRE FOR WINDING
What is USTC wire? It is insulation wire covered with one layer or multi layer insulating fiber (nylon, polyester fiber, natural silk and adhesive silk) on the surface of single enameled wire or stranded wire.USTC wire is a special type of wire used in electronics. The wire is designed to reduce the skin effect and proximity effect losses in conductors. It consists of many thin wires, individually coated with an insulating film and twisted or woven together, following a carefully prescribed pattern often involving several levels (groups of twisted wires are twisted together, etc.).The size range we can make is 0.03-0.8mm, and strands number is 2-4000.
