Abstract (en)
[origin: EP0702378A2] The chip inductance has a solid core part of ferromagnetic or electrically non-conductive material, especially ferrite, ceramic or plastic. The core part has a winding space for single or multilayer windings. The winding ends (9) are welded to contact elements on the front face. The winding ends are fixed to the contact elements using indirect laser welding. The contact elements have a coating of a solder metal. The contact elements also have a recess (7) which is the on and off winding site and also acts as shielding and welding material for the indirect laser welding.
