Abstract

A common mode choke () comprises a magnetic core () and a first (W) and a second (W) winding of insulated wire having the same number of turns wound on the magnetic core. The turns of each winding are numbered consecutively and arranged in at least two layers, of which a first layer of turns is wound directly on the magnetic core and a second layer of turns is wound around a section of the first layer. The two layers are arranged such that the difference between the highest number of a turn in the second layer and the lowest number of a turn in the section of the first layer on which the second layer is wound is less than or equal to 50% of the number of turns in the first layer. In this way, the effect of the parasitic capacitance between the layers is minimized.
