RCA 83,439 A signal suppression component such as a ferrite shield bead includes a cylindrical magnetically permeable member that has a longitudinal passage formed through it. The passage is filled with an elastic silicone rubber material. When the component is placed on a conductor or component lead, the elastic material forms a damping layer between the conductor and the permeable member to prevent audible vibration of the element due to current flow in the conductor. Such a component is especially useful in a line rate deflection circuit and in a resonant retrace power supply circuit. |
