Abstract
An inductor device includes a first face, a first inductive path, and magnetic permeable material. The first face couples the inductor device to a circuit board. The first inductive path extends between a first terminal on the first face to a second terminal on the first face. A portion of the first inductive path is exposed on a second face of the inductor device. The second face is disposed opposite the first face. The second face supports dissipation of heat conveyed by the first inductive path from the first face to the second face. The magnetic permeable material is disposed between the first face and the second face and carries magnetic flux associated with the first inductive path.
Claims21
An inductor device comprising:
- a first face operative to couple the inductor device to a circuit board;
- a first inductive path extending between a first terminal on the first face to a second terminal on the first face, a portion of the first inductive path exposed on a second face of the inductor device, the second face disposed opposite the first face, the second face operative to provide dissipation of heat conveyed by the first inductive path from the first face to the second face;
- and
- magnetic permeable material disposed between the first face and the second face, the magnetic permeable material operative to carry magnetic flux associated with the first inductive path.
A method comprising:
- fabricating a first inductive path of an inductor device to include a first face operative to couple the inductor device to a circuit board;
- fabricating the first inductive path to extend between a first terminal to a second terminal on the first face, a portion of the first inductive path exposed on a second face of the inductor device, the second face disposed opposite the first face and operative to provide dissipation of heat conveyed by the first inductive path from the first face to the second face;
- and
- fabricating the first inductive path to include magnetic permeable material disposed between the first face and the second face.
An inductor device comprising:
- a first face operative to couple the inductor device to a circuit board;
- a first inductive path extending between a first terminal on the first face to a second terminal on the first face;
- a second inductive path extending between a third terminal on the first face to a fourth terminal on the first face, the second inductive path magnetically coupled to the first inductive path via magnetic permeable material disposed between the first face and the second face;
- and
- at least one void in the magnetic permeable material, the at least one void disposed between the first inductive path and the second inductive path.
