摘要： The present invention relates to inter alia to a conductor having at least two windings where each of the two windings preferably has layered configuration of turns, where each layer of a winding preferably is serially connected. Further, layers are typically distanced from each other, preferably by use of layer spacers, which preferably provide a void, or a number of voids, in between each layers. Conductors according to the present invention have shown to lessen, such as reducing parasitic capacitance.
