ABSTRACT:
A signal suppression component such as a ferrite shield bead includes a cylindrical magnetically permeable element that has a passage formed through it. The passage is filled with an elastic silicone rubber compound. When the component is placed on a conductor or component lead, the elastic material forms a dampening layer between the conductor and the permeable element to prevent audible vibration of the element due to current flow in the conductor.
