Coupled inductor structures utilizing magnetic films

An inductor 100 is disclosed, including a first wire 101a, a second wire 101b parallel to the first wire, a non-conductive material 104 covering first and second wires, and a shell including an upper portion 102 and a lower portion 103, each including at least one magnetized layer, covering a portion of the non-conductive material. The shell includes a gap 105a, 105b between upper and lower portions at which the non-conductive material is not covered. Preferably, the magnetized shell comprises a channel (606, Figure 6) formed in the upper portion of the shell between first and second wires. The shell may comprise further gaps (205c, 205d, Figure 2) in the upper and/or lower portions at which the non-conductive material is not covered. The upper portion of the shell may extend past ends of the lower portion (Figure 3). The upper portion of the shell may include a plurality of magnetized layers each separated by a layer of non-conductive material (Figure 4).
