Abstract:
A side by side coil inductor comprising:a first coil comprising a plurality of conductive first coil segments positioned one above the other, said first coil segments being connected together in series; a second coil comprising a plurality of conductive second coil segments positioned one above the other, said second coil segments being connected together in series; said first and second coil being in side by side position relative to one another and being connected together in series; a top ferrite layer; a bottom ferrite layer; at least one middle ferrite layer between the top ferrite layer and the bottom ferrite layer; each of the at least one middle ferrite layer having a first via hole for connecting first coil segments in series and a second via hole for connecting second coil segments in series; and each of the at least one middle ferrite layers being separated from adjacent ferrite layers only by first coil segments and second coil segments.
