USTC / UDTC 0.04mm*270 Enameled Standed Copper Wire Silk Covered Litz Wire

This electromagnetic stranded wire is a customized wire, that is used in high frequency transformers, the original purpose is to solve the “skin effect”. When there is alternating current or alternating electromagnetic field in the conductor, the current distribution inside the conductor is uneven, and the current is concentrated in the "skin" part of the conductor, that is to say, the current is concentrated in the thin layer on the outer surface of the conductor. The closer to the conductor surface, the greater the current density. , the current inside the conductor is actually smaller. As a result, the resistance of the conductor increases, and so does its power loss. This phenomenon is called the skin effect. Use multiple strands of thin wire in parallel instead of a single wire to reduce the effect of skin effect.
