Abstract:
A surface mount power inductor component for a circuit board includes a magnetic body, at least one conductive coil, and surface mount terminations for completing an electrical connection between the conductive coil and the circuit board. One of the body and the surface mount terminations is configured to accommodate a separately provided component in a vertically stacked relation with the separately provided circuit board component being located between the circuit board and the body.
Abstract:
A surface mount power inductor includes a preformed conductive winding clip and first and second-shaped core pieces. The core pieces may be configured to reduce unbalanced force experienced in the power inductor in certain types of power management circuitry. Reduction in the unbalanced force reduces vibration of the power inductor in use, and in turn reduces acoustic noise as the power inductor operates.
Abstract:
A magnetic component and a method for manufacturing a low profile, magnetic component. The method comprises the steps of providing at least one sheet, coupling at least a portion of at least one winding to the at least one sheet, and laminating the at least one sheet with at least a portion of the at least one winding. The magnetic component comprises at least one sheet and at least a portion of at least one winding coupled to the at least one sheet, wherein the at least one sheet is laminated to at least a portion of the at least one winding. The winding may comprise a clip, a preformed coil, a stamped conductive foil, or an etched trace using chemical or laser etching. The sheet may comprise any material capable of being laminated and/or rolled, including, but not limited to, flexible magnetic powder sheets.
Abstract:
Magnetic components including pre-formed clips are described that are more amenable to production on a miniaturized scale. Discrete core pieces can be assembled with pre-formed coils and physically gapped from one another with more efficient manufacturing techniques.
