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.

Abstract: An electromagnetic component assembly includes a first magnetic core piece, a second magnetic core piece, and an inverted U-shaped conductive winding including a base section and first and second legs extending from base section.

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.

First and second surface mount terminals respectively extend perpendicular to the pair of winding legs in opposing directions to each other, such that each of them extends only on one of the first and second magnetic core pieces but not the other.

Abstract: This invention discloses a magnetically latching solenoid valve and a solenoid thereof. The solenoid includes a coil disposed around a bobbin and divided into two sections by a tap for adjustable pull and release forces to a plunger disposed therein. A first section of the coil, through magnetic induction, pulls the plunger toward a fixed stopper disposed at the lower end of the bobbin and coupled to a cylindrical yoke. A permanent magnet is disposed between the stopper and the yoke. On contact with the stopper, the plunger is held in place by the permanent magnet even after the current flow is removed from the first section of the coil. A second section of the coil, with a differing magnetic induction, returns the plunger.
