Patent Abstract

The filter (101) has a main filter circuit filtering unwanted frequency portions e.g. electromagnetic compatibility relevant disturbances, and a coordinated circuit arrangement (102) e.g. resonant circuit, influencing a filter characteristic of the filter circuit. The circuit arrangement is fixed in series connection with a throttle (L-B) i.e. current-compensated throttle, and a capacitor (C-B). The throttle is wound on a core of the main filter circuit. An additional coil is attached on the core of the filter circuit for uncoupling induced voltage supply to the circuit arrangement.
