An interference suppressor ( 10 ) for suppressing high-frequency interference emissions of a direct current motor ( 26 ) that is drivable in a plurality of stages and/or directions is proposed, having a plurality of capacitors ( 16 ) located on a first side ( 12 ) of a printed circuit board ( 14 ) and having a plurality of first conductor tracks ( 18 ), located on the first side ( 12 ) of the printed circuit board ( 14 ), for putting the various capacitors ( 16 ) into contact with a ground terminal ( 20 ), and having a first terminal ( 22 ) and at least one further terminal ( 24 ) for the individual stages of the direct current motor ( 26 ), the first terminal ( 22 ) and the at least one further terminal ( 24 ) being put into contact with a first connection line ( 48 ) for the first stage and at least one further connection line ( 50 ) for the at least one further stage of the direct current motor ( 26 ). The interference suppressor ( 10 ) is characterized in that a ground face ( 34 ) is located on a further side ( 32 ), diametrically opposite the first side ( 12 ), of the printed circuit board ( 14 ), and the first connection line ( 48 ) and the at least one further connection line ( 50 ) are fed through in insulated fashion relative to the ground face ( 34 ).
