摘要： An inductive component is provided, including: a winding; and a plurality of adjustment bodies configured to adjust an inductance of the inductive component, the adjustment bodies including a ferromagnetic material and surrounding at least some regions of the winding, the inductance being adjusted via a shape and/or a position and/or a number of the adjustment bodies, and a filling body including a non-magnetic material is disposed between at least two of the adjustment bodies.

摘要： An inductive component is provided, including: a wire winding, around which a magnetic foil is wrapped; an electrical shielding, which surrounds the magnetic foil, the magnetic foil including at least one magnetic layer, the at least one magnetic layer including a magnetic material, and the magnetic material being a nanocrystalline iron alloy; and a non-magnetic and non-conductive insulating layer, which includes a plastic and which is disposed between the magnetic foil and the wire winding. A method for adjusting an inductance value of an inductive component is also provided.

摘要： An inductive component is provided, including: a coil former including a base body and being a carrier for a winding wire; an electrically insulating foil, some regions of the body being wrapped with the foil; and a winding of the wire around the coil former, such that the foil is between the wire and the body, and extends over a maximum of two thirds of a maximum possible effective length of the foil with which the foil would be present underneath the entire winding such that in some regions the wire is disposed over the foil, and in some regions the wire is disposed directly on the body, and such that a diameter of the winding in a region in which the wire is disposed over the foil is increased. A method for adjusting an inductance value for a group of inductive components of a same design is also provided.
