An inductor structure is provided that is positioned within a via of a printed circuit board. The inductor structure includes a via extending through a printed circuit board. The inductor structure includes at least one coil of an electrically conductive material beginning at a first opening to the via continuously present on a sidewall of the via encircling a center of the via extending to a second opening of the via opposite the first opening of the via. It further includes at least electrode present in contact with an end of the coil at said first or second opening.
