Abstract: In an electronic circuit, comprising electrical and electronic components and their connecting lines (3) on a printed circuit board (2), in which case a shielded housing encloses the electronic circuit, attenuating radiofrequencies, in order to prevent interference which acts on the electronic circuit and interference which is caused by the electronic circuit, in particular for use in a combination display instrument in a motor vehicle. Connecting lines (3) from the electronic circuit on the printed circuit board (2) are passed out of the shielded housing (1), connecting means (5) outside the shielded housing (1, 15) are connected to the connecting lines (3), and shielding is provided which reduce or suppress the ingress of radio-frequency interference into the shielded housing (1) and the emission of radio-frequency interference from the shielded housing (1).

Abstract: A electronic circuit for an automobile, in particular in an instrument cluster, is disclosed. The electronic circuit comprises a computer having at least one microprocessor and application-specific integrated circuits and it is arranged in a shielding housing for suppression of electromagnetic interference. For improved removal of heat and high-frequency decoupling, surface areas of the external shielding are electrically and mechanically closely coupled to corresponding surface areas on the conducting path and, in addition, the incoming and outgoing lines which are subject to interference are protected by suitable filters.
