The mains filter comprises coils with windings which are arranged on substrates, for example conventional thin printed circuit boards, as conductor tracks. A coil can comprise one or more substrates, which are in contact with one another in the case of a plurality of substrates. In the centre, the substrates have an opening through which a core is passed. With an appropriate number of windings, one substrate is sufficient for one winding, so that only one substrate per coil is required for the mains filter. The two substrates for the two coils can be of identical design, in particular, the input and the output for a coil being arranged on a substrate in the region of opposite corners. The core used can be a narrow E/E core or E/I core, so that the space requirement for the filter on a circuit board is very low.
