2USTC-F 155 0.04mm * 420 strands High Frequency Nylon Served Copper Litz Wire
This wire is covered with nylon yarn, the single wireis 0.04mm enameled copper wire. We use polyurethane lacquered single wire that can be directly welded, so that the silk covered litz wire has good temperature resistance, and the maximum temperature resistance can reach 155 degrees. If you need wires with higher temperature resistance, we also provide 180 degree and 200 degree options. This wire is twisted by 420 strands.
