  • Publication number: 20240128012
    Abstract: Surface mount inductor components include pre-formed coils with integrated bottom sunken features and simply shaped core pieces configured to create magnetic gaps in an assembled core structure around the coils when desired. The magnetic gaps interrupt flux paths in the operating components and provide swing-inductor functionality. The magnetic gaps may be reliably and economically provided in the form of interior or exterior grooves or depressed surfaces that may be easily formed in the core pieces while also facilitating ease of assembly of the inductor components.

  • Publication number: 20230100831
    Abstract: An inductor component includes a single conductive coil configured to establish surface mount connections with a circuit board. A magnetic core structure receives and encloses first and second legs of the single conductive coil, and first and second physical gaps are respectively formed in the magnetic core structure and are located to respectively intersect a flux path generated by current flow in only one of the elongated first or second legs. By virtue of the pair of physical gaps the inductor component operates as a swing-type inductor component with multiple steps of inductance roll off.
