Abstract

A shielding element and a decoupling element are integrated into a combined attenuation element. The shielding element may be a shielding foil, preferably made of copper. The attenuation element may include a flexible backing foil, preferably a plastic backing foil which supports the shielding foil. It may also include an adhesive layer with which the electronic component is affixed to a housing. The physical properties of all elements of the attenuation element are attuned to one another such that it simultaneously attenuates both electromagnetic alternating fields as well as mechanical oscillations.
