An electronic component includes a solid core part having a perpendicular prismatic spatial shape and lateral surfaces, the core part having a recess in the form of a blind hole formed therein defining a winding space, and electrical contact layers disposed on at least some of the lateral surfaces of the core part.

Electronic component, especially for a chip inductance

A method for bonding a lacquer insulated wire to a metallic support is disclosed. The method is carried out in two steps: First, the wire is exposed to ultrasonic energy so that the lacquer is broken up and the wire is deformed in a certain area and welded to the support. Then the entire area of deformation is enclosed with a thixotropic adhesive. In preferred embodiments, the method is used for bonding the winding wire of a HF-inductor coil with contact elements shaped as wires or lugs.

Method for bonding an insulated wire element on a contact

An electronic component such as a chip inductor, in particular an air core coil, RF choke and transformer is disclosed having a solid core portion (1) of the ferromagnetic or electrically nonconducting material, with a winding space to be wound in one or more courses and recessed relative to parallel end faces (2, 2) of the core portion. The end faces (2, 2) have dovetail-shaped cutouts (3, 3) located within the outside portion of these end faces for receiving tab-like electric contact elements (5, 5). These electrical contacts may be glued or wedged into these cutouts and retained therein under the action of resilient properties of the cutout elements.
