An interference suppressor for suppressing high-frequency interference emissions of a direct current motor that is drivable in a plurality of stages and/or directions, comprising a plurality of capacitors located on a first side of a printed circuit board, a plurality of first conductor tracks located on the first side of the printed circuit board for putting the capacitors into contact with a ground terminal, a first terminal and at least one further terminal provided for individual stages of the direct current motor, and put into contact with a first connection line for a first stage and at least one second connection line for at least one second stage of the direct current motor, a ground face located on a second side, diametrically opposite the first side of the printed circuit board, with the first connection line and the at least one second connection line fed through in insulated fashion relative to the ground face wherein the ground face is electrically connected via through-plated holes embodied as via-holes to the ground terminals of the capacitors on the first side of the printed circuit board, and wherein the capacitors are arranged in at least one group, in which the capacitors are located in a C-shaped arrangement.
