Claim 6:
7. An inductor structure, comprising:
a first magnetic thin film core structure having a first magnetic thin film core, a first magnetic thin film core extension, and a second magnetic thin film core extension, wherein the first and second thin film core extensions surround the first magnetic thin film core, wherein the first magnetic thin film core extension connects to the first magnetic thin film core at a plurality of first locations situated along a first side of the first magnetic thin film core, and wherein the second magnetic thin film core extension connects to the first magnetic thin film core at a plurality of second locations situated along a second side of the first magnetic thin film core that is opposite from the first side of the first magnetic thin film core;
a second magnetic thin film core structure connected to the first magnetic thin film core structure and having a second magnetic thin film core, a third magnetic thin film core extension, and a fourth thin film core extension, wherein the third and fourth magnetic thin film core extensions surround the second magnetic thin film core, wherein the third magnetic thin film core extension connects to the second magnetic thin film core at a plurality of third locations situated along a third side of the second magnetic thin film core, and wherein the second magnetic thin film core extension connects to the second magnetic thin film core at a plurality of fourth locations situated along a fourth side of the second magnetic thin film core that is opposite from the third side of the second magnetic thin film core; and
a conductive winding wound around the first and second thin film cores to form windings for the inductor structure.
