Abstract
The invention relates to an electrical filter element (1) for filtering alternating voltage interference. The electrical filter element (1) comprises two dielectric circuit board substrates (11, 12) having a magnetic core (13) arranged between the circuit board substrates. The magnetic core (13) has a material-free inner region (13a), in which electrical connection elements (21-24) are provided between the two dielectric circuit board substrates (11, 12). Furthermore, electrical connection elements (31, 32) can also be provided between the two dielectric circuit board substrates (11, 12) in an outer region of the magnetic core (13).
