Abstract:
1. A method of manufacturing an inductive device, said method comprising: providing at least three substrates comprising a top substrate, a bottom substrate and one or more middle substrates, at least one of said at least three substrates comprised of an exterior surface which is at least partly copper plated, with said at least one substrate having one or more windings formed thereon; disposing a plurality of conductors in the at least one of said three substrates, said conductors disposed so as to extend from said exterior copper plated surface and substantially through at least one or more said substrates; disposing a magnetically permeable core at least partly between two or more of said at least three substrates; disposing a second magnetically permeable core at least partly between two or more of said at least three substrates; and disposing an incorporated electronic component onto at least one of said at least three substrates; wherein said second magnetically permeable core in combination with said at least three substrates, said conductors, said incorporated electronic component, and said magnetically permeable core, form a complete filter circuit.
