Abstract
An apparatus for reducing electromagnetic interference associated with a signal-conducting cable includes a ferrite bead and a one-piece molded encasement covering the ferrite bead. The encasement includes a number of ribs located within a longitudinal aperture of the ferrite bead. The ribs protrude radially inward to secure the apparatus to the cable and to coaxially align the cable within the aperture. In a preferred embodiment, the encasement and ribs are integrally formed from a resilient material.
