1. An inductive device, comprising:
- a plurality of substrates, said substrates collectively having a plurality of conductive pathways formed therein comprised of a first conductive pathway and a second conductive pathway, each of said plurality of conductive pathways defined by a plurality of vias comprised of a plurality of outer vias and a plurality of inner vias; and
a plurality of magnetically permeable cores comprising a first magnetically permeable core and a second magnetically permeable core, said cores disposed at least partly between said plurality of substrates;
wherein said magnetically permeable cores are stacked in a substantially vertical fashion such that at least a portion of said magnetically permeable cores are substantially parallel yet not co-extensive; and
wherein said first magnetically permeable core is associated with said first conductive pathway and said second magnetically permeable core is associated with said second conductive pathway, said first and second conductive pathways being distinct from one another.

Abstract
A wire-less inductive device and methods of manufacturing and use are disclosed. In one embodiment, the inductive device comprises a plurality of through-hole vias which act to replace windings disposed around a magnetically permeable core. In another embodiment, the inductive device comprises a plurality of connection elements disposed or formed within channels which act as windings disposed around a magnetically permeable core. In a second aspect of the invention, a method of manufacturing the aforementioned inductive devices is disclosed. In a third aspect of the invention, an electronics assembly and circuit comprising the wire-less inductive devices are disclosed.
