Abstract

An electromagnetic compatibility (EMC) filter used in a hybrid technology circuit component, having current-carrying lines and a ground conductor, for protection against electromagnetic interference. The current-carrying lines and ground conductor are arranged on a ceramic plate. The current-carrying lines are covered by a dielectric, which in turn, is covered by an upper metal screen in electrical contact with the ground conductor. A lower metal screen is arranged on the ceramic plate beneath the current-carrying lines and is in electrical contact with the ground conductor.
