摘要： A bobbin provides secure attachment of a magnetic component to a printed circuit board. The circuit board includes a set of slotted apertures and a set of tubular apertures. The bobbin includes at least two pin rails and a plurality of standoffs proximate each pin rail. L-shaped pins are attached to one of the pin rails. Straight pins are attached to the other pin rail. The component further includes a core, and at least one winding. The L-shaped pins are shaped to pass through and slide within the set of slotted apertures. The L-shaped pins engage the bottom surface of the circuit board when the straight pins are inserted through the set of tubular apertures (i.e., in a secured position). In the secured position, the magnetic component is held in place against the top surface of the circuit board and provides a soldering area for mounting on the bottom surface.

摘要： A magnetic assembly includes a single bobbin structure that supports a first coil and a second coil. A first E-core has a center leg positioned within the first coil. A second E-core has a center leg positioned within the second coil. An I-core is positioned between the first E-core and the second E-core. The I-core completes a first set of magnetic paths between the center leg and outer legs of the first E-core and also completes a second set of magnetic paths between the center leg and outer legs of the second E-core. The two E-cores and the I-core are stacked in a vertical E-I-E configuration with respect to a common set of pin rails. In one embodiment, the first coil and the first E-core are configured as a transformer; and the second coil and the second E-core are configured as an inductor.

摘要： A magnetic assembly includes a bobbin with two end flanges. A passageway extends longitudinally between the end flanges. An inner core extends through, and is centered in, the passageway. The inner core has first and second end surfaces, each surface proximate to one of the end flanges. A rectangular outer core is positioned around the bobbin with inner surfaces of the outer core close to the outer surfaces of the end flanges of the bobbin. A respective gap is formed between each end of the inner core and the adjacent inner surface of the outer core. The passageway includes crushable ribs that secure the inner core within the passageway. The outer surfaces of the end flanges include crushable ribs that secure the core with respect to the bobbin. The passageway and inner core may have an oval-shaped profile. The passageway and inner core may have a circular profile.

摘要： A magnetic connector assembly has two independent magnetic components sharing a common core structure. The magnetic assembly includes first and second bobbins, and includes a magnetic core. The magnetic core includes first and second core halves, each half including a main core body, a first outer leg, a second outer leg, and a middle leg. The first outer leg fits within a passageway of the first bobbin. The second outer leg fits within a passageway of the second bobbin. The middle leg fits between the two bobbins.

摘要： A low profile inductive apparatus is provided via one or more traces in a printed circuit board, the one or more traces defining inductive winding turns about an aperture, and a core comprising an elongate core member configured for positioning through the aperture of the circuit board. The core may be press fit with respect to the printed circuit board, or alternatively the elongate core member and the aperture may be reciprocally threaded. In an embodiment, core flanges may be provided on opposing sides of the printed circuit board, with the elongate core member connected between the core flanges and extending through the aperture. The number of inductive winding turns relates to a required inductance of the inductor when the elongate core member is positioned through the aperture, and a width and thickness of the windings corresponds to a required carrying capacity of the inductor.

摘要： A common mode choke assembly includes a main core, a shunt core, and first and second two-piece bobbins. The main core has a generally rectangular main core body, and first and second core riser portions. The first and second core riser portions are connected to opposite ends of the main core body. The first core riser portion includes a first riser notch and the second core riser portion includes a second riser notch aligned with the first riser notch. The shunt core spans between and is positioned within the first and second riser notches. The first and second two-piece bobbins are positioned on opposite sides of the main core body adjacent to the first and second core riser portions. Each two-piece bobbin includes at least first and second end flanges, a passageway, and a mating surface. The assembly further includes a mounting header for receiving the main and shunt core.

摘要： A magnetic component has a variable inductance over a range of DC bias currents. The component includes a bobbin with a coil positioned around a passageway between first and second end flanges. First and second E-cores (either conventional or EFD E-cores) have respective middle legs positioned in the passageway with end surfaces of the middle legs juxtaposed within the passageway and spaced apart by a first magnetic gap. An I-bar is positioned in the passageway parallel to and spaced apart from respective first longitudinal surfaces of the middle legs to form a second magnetic gap between the I-bar and the longitudinal surface of the middle leg of the first E-core and to form a third magnetic gap between the I-bar and the longitudinal surface of the middle leg of the second E-core. The magnetic component provides higher inductances for lower bias currents and provides lower inductances for higher bias currents.

摘要： A common mode inductor includes a bobbin with two windings. A first winding is positioned between a first end flange and a first offset flange. A second winding is positioned between a second end flange and a second offset flange. The windings are spaced apart by a center section without windings. A pair of E-cores, each having a pair of outer legs and a center leg, are positioned in a passageway of the bobbin such that the center leg of each E-core is surrounded by a respective one of the two windings. An I-bar is positioned in the center section of the bobbin between the two offset flanges with the I-bar perpendicular to the outer legs and the center legs of the two E-cores. The I-bar core increases leakage inductance between the two windings to improve the suppression of electromagnetic interference caused by common mode noise in the two windings.
