Abstract
A filter device for at least one electrical line connectable externally to a housing includes at least one contact pin for connecting the externally connectable electrical line to a multilayer printed circuit board having at least one support layer and at least one conductor layer, the contact pin having a part thereof located at a side of the filter device and being affixed to the printed circuit board, at least one outer layer of the printed circuit board being formed as either a holohedral or a grid-shaped shielding layer, respectively, the shielding layer being in an electrically conductive contact-connection with the housing. A contact pin of a conductor path of the conductor layer conductable to the outside is connected to the printed circuit board, the contact pin being arranged without electrical connection to the shielding layer. An electrical filter element is connected to the contact pin, the filter element having an electrical property corresponding to a selected value of the corresponding filtering, the filter element being electrically conductively connected to the shielding layer.
