摘要： An electromagnetic component such as a power inductor includes first and second magnetic core pieces and a preformed coil winding therebetween. The preformed coil winding includes a top winding section and a pair of coplanar winding legs defining a U-shaped winding section therewith. The pair of winding legs are oriented perpendicular to a circuit board in use. 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.

摘要： An inductor includes discrete magnetic core pieces fabricated from different magnetic materials having different magnetic properties. An inverted U-section conductive coil includes a top section and first and second legs to establish a surface mount connection to a circuit board, and the discrete magnetic core pieces are assembled around the inverted U-section conductive coil. The first and second discrete magnetic core pieces are operable to reach magnetic saturation at respectively different current loads applied to the coil when the circuit board is energized, imparting multiple steps of inductance rolloff response to a range of current loads.

摘要： 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. One of the first and second magnetic core pieces is configured to receive the base section. The first and second magnetic core pieces are gapped from one another to define a first gap, and one of the first and second magnetic core pieces includes a second gap that, in combination with the first gap, allows the component to be operated at more than one stable open circuit inductance (OCL) corresponding to different current loads.

摘要： An electromagnetic component such as a power inductor includes first and second magnetic core pieces and a preformed conductive coil winding. The coil winding includes a U-shaped winding section including a top winding section and a pair of winding legs extending from opposing ends of the top winding section. The winding legs extend coplanar to one another and are oriented perpendicular to a circuit board in use. The legs are located between the first and second magnetic core pieces, and the top winding section is bent to extend perpendicularly to the plane of the pair of winding legs.
