Abstract
A vehicular mirror actuator for adjustably positioning a mirror includes at least one motor with a casing and one or more power leads for powering the motor. An electromagnetic interference suppressor is included in the mirror actuator assembly and is mounted externally to the motor casing. The interference suppressor may include either a choke or at least one ferrite bead coupled between the power lead and the motor. The interference suppressor may be positioned either internally within the actuator housing, or externally to the actuator housing. Alternatively, the interference suppressor may include a metallic lining that surrounds the vehicular mirror actuator and which includes at least one feed-through capacitor coupled to said metallic lining and a source of power.
