In most cases, high-frequency coils are wound in layers with fewer turns. Usually these litz wires are covered with natural silk or nylon wire, so that the wire can remain round on the coil bobbin under a certain winding tension, so that accurate layered winding can be realized. In some occasions, uncoated litz wire (ordinary litz wire) can also be used. At this time, special attention should be paid to choosing a compact and dimensionally stable structure. However, the Litz wire will inevitably undergo small elliptical deformation, so it is necessary to appropriately reduce the total outer diameter of the coil as compensation. Therefore, when the maximum outer diameter of the coil is constant, the litz wire with a coating layer has a higher conductor cross-sectional area than the litz wire without a coating layer.
