Litz Wire

The word "Litz" is derived from the German word "Litzendraht" meaning woven wire. It refers to wire consisting of a number of individually insulated magnet wires twisted or braided into a uniform pattern, so that each strand tends to take all possible positions in the cross-section of the entire conduct

This multi-strand configuration or Litz construction is designed to minimize the power losses exhibited in solid conductors due to "skin effect". Skin effect refers to the tendency of current flow in a conductor to be confined to a layer in the conductor close to its outer surface. At low frequencies, skin effect is negligible, and current is distributed uniformly across the conductor. However, as the frequency increases, the depth to which the flow can penetrate is reduced. Litz wire constructions counteract this effect by increasing the amount of surface area without significantly increasing the size of the conductor. After more wired are twisted, it forms a lower circumferential epidermis in order to decrease the skin effect and the equivalent register of high frequency, It will be easier to overcome the difficulties in designing coils that shall have higher pressure proof and higher resistance. Litz wire sizes are often expressed in abbreviated format: N / XX, where N equals the number of strands and XX is the AWG (American Wire Gauge) size of each strand. For example, a typical size of a Litz-wire would be expressed as "12 / 38" or twelve strands of 38 AWG (0.100 mm). Insulation and serving/jacketing options are listed after the size, for example, 12/38 Single Nylon Served.
