The disclosure relates to a filter circuit on an electric motor which has electrical connections at a connection end for connection to a supply voltage (U). The filter circuit consists of at least one capacitor bridge arranged between the connections of the electric motor for radio interference suppression. For increased electromagnetic compatibility (EMC), the filter circuit is arranged on a circuit board and held on the connection end of the electric motor. The circuit board has a capacitor bridge with interference suppression capacitors, which is connected between the electrical connections of the electric motor, wherein an interference suppression capacitor has a longitudinal axis between its electrical connections in the longitudinal direction. The interference suppression capacitors are arranged on the circuit board with their longitudinal axes aligned in different spatial directions.
