Abstract

The device has at least one inductance in the form of winding material with wire ends (7,8). The winding material contains a part (1) that is both magnetic and also provides the fixing for the wire ends, whereby the part is made of one material throughout. The part is made from a compound material that contains ferrite and polymers.
