Abstract
Abstract The invention relates to a device for filtering a high-frequency conductor from a high-frequency space by a capacitor (71). The filtering capacitor (71) is in the form of a chip capacitor and is secured to a circuit board (1). A first contact surface (73) of the chip capacitor (71) is electrically contacted by soldering with the separation wall (19) closing the high-frequency space. The conductor (77) to be filtered is passed along a second contact surface (75) of the chip capacitor (71) so as to be electrically contacted by soldering along a largest possible surface. The conductor (77) to be filtered can be in the form of a planar conductor. The invention is applicable in particular in audio and video tuners.
