A filter device (10) for filtering high-frequency interferences, such as due to switching flanks of a DC converter, has a current path (4) between an input (2) and an output (3), and an inductor (L) in the current path (4), wherein the inductor (L) is disposed in the current path (4) as a first component and is connected to the input (2), and wherein a reverse polarity protective diode (D) is disposed in series with the inductor (L) downstream thereto.
