ABSTRACT:
Inductive electrical components fabricated by PWB techniques of ferromagnetic core or cores are embedded in an insulating board provided with conductive layers. Conductive through-holes are provided in the board on opposite sides of a core. The conductive layers are patterned to form with the conductive through-holes one or more sets of conductive turns forming a winding or windings encircling the core. The conductive layers can also be patterned to form contact pads on the board and conductive traces connecting the pads to the windings.
