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.
