Abstract: An electromagnetic filter assembly for attenuating electromagnetic interferences can comprise a base plate comprising a first opening configured to be penetrated by a first conductor from which an electromagnetic interference at least partially originates, wherein the base plate comprises an electrically non-conductive carrier layer, an electrically conductive first layer section, and an electrically conductive second layer section, wherein the first layer section comprises a shielding interface configured to connect the first layer section to a shielding in an electrically conductive manner, wherein the second layer section comprises a first conductor interface configured to connect the second layer section to the first conductor in an electrically conductive manner, and wherein the first layer section and the second layer section are capacitively coupled via at least two discrete capacitor elements.
