Abstract:
1. An inductor comprising: a planar ferrite core; a first group of one or more grooves formed in a first side of the ferrite core; a second group of two or more grooves formed in a second side of the ferrite core, wherein the grooves in the first and second groups are oriented such that each groove in the first group overlaps with one or two corresponding grooves in the second group; a first plurality of vias communicating through the ferrite core between the first and second sides of the ferrite core, wherein each via is located where a groove in the first group overlaps with a groove in the second group; and a conductive material disposed in the first and second groups of grooves and the vias, wherein the conductive material disposed in the first and second groups of grooves and the vias form an inductor coil.
