Abstract
Various magnetic thin film inductor structures are disclosed that include one or more magnetic thin film (MTF) materials. During operation, an electric field passes through one or mare conductive windings which, in turn, generates a magnetic field for storing energy within these magnetic thin film inductor structures. The magnetic thin film (MTF) materials within these magnetic thin film inductor structures effectively attract magnetic flux lines of this magnetic field. As a result, any magnetic leakage resulting from the magnetic field generated by these magnetic thin film inductor structures onto nearby electrical, mechanical, and/or electro-mechanical devices is lessened when compared to magnetic leakage resulting from the magnetic field generated by other inductor structures not having the one or more MTF materials.
