Abstract: The present invention relates to a filter component (40) for use in an electric circuitry, the filter component comprising a ferromagnetic body (14), an inductor and a printed circuit board, PCB, (20). The ferromagnetic body has a first side (14a) and a second side (14b), the second side opposing the first side, and first and second connection pins (18a, 18b) arranged on the first side of the ferromagnetic body thereby defining a surface area (17) comprising at least an area of the first side between the first and a second connection pins (18a, 18b). The inductor is integrated in the ferromagnetic body (14) and connected to the first and second connection pins (18a, 18b), and the PCB (20), has a first PCB side (20a) and a second PCB side (20b), the second PCB side opposing the first PCB side. At least one component of the electric circuitry is arranged on the PCB (20), and the second PCB side (20b) is arranged on the surface area (17) between the connection pins (18a, 18b).
