An inductive filtering device comprising a plurality of grouped electrical conductors, each intended to carry a different voltage, and at least two toric magnetic cores, each formed around a central void, the two magnetic cores having different magnetic lengths, the electrical conductors being wound together around both magnetic cores by passing through the central voids of both magnetic cores, wherein the toric magnetic cores are formed in different materials, the material of the magnetic core having the shortest magnetic length exhibiting a maximum relative magnetic permeability lower than or equal to 3000 and lower than that of the material of the magnetic core having the longest magnetic length.
