A multilayer conductor includes at least one separation dielectric layer and a plurality of conductor layers stacked in an alternating manner. Each of the plurality of conductor layers includes a first conductor sublayer and a second conductor sublayer separated from the first conductor sublayer by a sublayer dielectric layer. The second conductor sublayer at least partially overlaps with the first conductor sublayer in each of the plurality of conductor layers. The multilayer conductor is included, for example, in a device including a magnetic core adjacent to at least part of the multilayer conductor.
