1. 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.
