An inductive component, which has an annular core having a core cross section and made of a soft-magnetic material and a coil surrounding the core is provided. The coil is composed of two electrically conductive sections. The sections each have a basic U shape with two limbs, of which the first limb is longer than the second limb and the first limb is curved and towards the end of same projects away from a plane defined by the basic U shape. The sections are pushed onto the core next to one another so that the basic U shape of each section surrounds the core cross section on three sides. The first limb of a section is mechanically and electrically connected to the second limb of the other section. A method for producing a component of this kind is also described.

The invention relates to a high-pass branch () of a frequency separating filter for ADSL systems comprising inductive components () which dispose of magnet cores made of a soft magnetic amorphous or nanocrystalline. As a result, frequency separating filters are provided which comprise small structural shapes and which have especially beneficial properties in the relevant frequency and temperature range.

In a magnetic sensor device, a positioning element is provided with receptacles for receiving one magnetic field sensor element each. The positioning element and the magnetic field sensor elements are manufactured in a way that they fit exactly together so that the positioning element exactly positions the sensor elements with respect to each other. The magnetic field sensor elements may be manufactured separately before they are put together to build the magnetic field sensor device.

A toroidal tape core is produced from magnetic sheets ( ) which may have slits ( ). In order to improve the behavior of the toroidal cores ( ) at high frequencies, the magnetic sheets ( ) have a high surface roughness. The surface roughness of each magnetic sheet ( ) is at least equal to the skin penetration depth at the frequency being used.

A magnetic distance sensor for acquiring the position of a test subject has an elongated magnetic core that contains crystalline strips and amorphous strips. A measuring winding supplied by a constant current source generates respective voltages, directed oppositely relative to one another, in two coils, so that a differential voltage arises dependent on the position of the test subject. A distance sensor that is insensitive to unwanted magnetic fields is thus obtained.
