NOISE SUPPRESSION CIRCUIT

摘要

The invention relates to a noise suppression circuit, especially for suppressing the noise generated by the wiper motor of a motor vehicle. The inventive circuit is provided with at least two capacitors (4, 5) which are placed between one common (1) and two separate connections (2, 3) and is provided with an impulse limit. In order to limit impulses, the series connection comprised of the cathode-anode section of a diode (6, 7) and of the cathode-anode section of a Zener diode (8) is connected in parallel to each capacitor. For the advantageous use as a noise suppression module, the inventive noise suppression circuit can be installed in a noise suppression device which is provided in a capacitor housing. The capacitor housing comprises three contact connections which are interspaced with a fixed spatial relationship to one another independent of the number of noise suppression components and can be cuboidal or cubical.
