Radio-interference suppression filters combine the characteristcs of capacitors and chokes in one unit. By adapting the chokes and capacitors induvidually to the interference-spectrum, an optimal suppression result is achieved. In order to increase the filter-effect it is also, additionally to the individual selection of capacitor and choke, common to design the filter as a 2-stage-filter. In principle the filters are distinguished in maingroups as follows.
