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.
