ABSTRACT:
An apparatus is disclosed which presents a high impedance to unwanted RF signals which may be otherwise coupled to jumper wires which traverse the boundary between RF shielded areas. Specifically, a conductor for connecting two circuits separated by a shield wall is surrounded by a ferrite material which is positioned to extend through an aperture of the RF shield.
