Embodiment Construction

[0114] figure 1 An exploded view of an integrated magnetics component 1 with an annular common mode core 2 is shown. Two windings 4 are wound around the common mode core 2 and pass through the winding window 3 . The bar-shaped differential mode magnetic core 5 comprises a surface 6 which, when placed in the remaining space of the winding window 3, is adjacent to each of the two windings 4 (see also figure 2 ). The surface 6 of the bar-shaped differential mode core 5 has the same distance to each of the two windings 4 as the common mode core 2 has. In other words, the two windings 4 are tightly wound around the common-mode magnetic core 2 , and the rod-shaped differential-mode magnetic core 5 is tightly fitted into the remaining space of the winding window 3 . Each of the two windings 4 comprises two terminals 7 (only one terminal is shown per winding), which are arranged through openings 8 of a printed circuit board (PCB) 9 .

Abstract

The invention discloses an integrated magnetic component, and the integrated magnetic component comprises a common mode inductance and a differential mode inductance. The common mode inductance is formed by a common mode core surrounding a winding window and at least two windings wound around the common mode core and through the winding window. The differential mode inductance is formed by the atleast two windings and a differential mode core being spaced from the common mode core by a gap. The differential mode core comprises at least one surface being adjacent to each of te at least two windings. Further, a filter for attenuating electromagnetic interference comprises an integrated magnetic component according to the invention. Even further, the integrated magnetic component according to the invention is used for attenuating electromagnetic interference, preferably in a vehicle, a data center, or a telecommunication unit. A method for manufacturing an integrated magnetic component according to the invention comprises two steps. One step comprises providing a common mode inductance formed by a common mode core surrounding a winding window, and at least two windings wound around the core and through the winding window. Another step comprises providing a differential mode core and spacing it from the common mode core by a gap, such that at least one surface of the differentialmode core is adjacent to each of the least two windings.
