Abstract (en)
[origin: EP0522475A1] The invention relates to an inductive component having at least two windings, and to a method for its production. In order to achieve a compact construction and a cost-effective production method, a winding stack (3) is proposed having an arrangement of insulating material layers (9) and layers of structured metal sheet (11) stacked one above the other. The structured metal sheets (11) represent flat, spiral windings (7,8) which are embedded between insulating layers (9) and are baked under the influence of temperature and pressure to form a winding stack (3). Electrical connections between the windings connections (13) and to external connections (4) are produced with the aid of connecting pins (6) which are pressed into holes (5) which are incorporated at right angles to the plane of the layer, and are in consequence cold-welded to the respective metal sheets (11). <IMAGE>
