A signal suppression component (38) such as a ferrite shield bead includes a cylindrical magnetically permeable member (33) that has a longitudinal passage (34) formed through it. The passage (34) is filled with an elastic silicone rubber material. When the component (38) is placed on a conductor or component lead (37), the elastic material (36) forms a damping layer (40) between the conductor (37) and the permeable member (33) to prevent audible vibration of the element due to current flow in the conductor (37). Such a component is especially useful in a line rate deflection circuit and in a resonant retrace power supply circuit. <IMAGE>
