Keeping in view the partial breaking of the supersymmetry of dyons in N=4 supersymmetric theories, which is due to the presence of a central charge in the algebra, and the mass of the BPS dyon in supersymmetric Yang-Mills theories, we have analyzed the ratios of charges of supersymmetric black holes with 1/4 of unbroken N=4 supersymmetry and demonstrated that in spontaneous breaking of the N=4 global supersymmetry to N=2, the parameters of electric and magnetic Fayet-Iliopoulos terms can be considered proportional to the electric and magnetic charges of the dyonic black holes.
