Description

Litz wire is a special type of wire used in electronics. It consists of many thin wires, individually coated with an insulating film and braided, thus increasing the surface area of the conductor and thereby reducing the skin effect and associated power losses when used with high-frequency applications. The ratio of impedance to resistance is increased, relative to a solid conductor, resulting in a higher Q factor at these frequencies. The word originated from litzendraht, German for woven wire. This type of wire is used to make inductors and transformers, especially for high frequency applications where the skin effect is more pronounced.
