ABSTRACT:
A valve metal electromagnetic interference filter (VMEIF). The filter comprises a porous valve metal pellet with at least three terminals extending therefrom. A dielectric layer at least partially circumvents the sintered porous valve metal pellet. A conductive layer at least partially circumvents the dielectric layer. A primary termination pad is in electrical contact with each lead. An inductor is in electrical contact with at least one lead between the sintered porous valve metal pellet and the primary termination pad. A secondary termination pad is in electrical contact with the conductive layer and a casing encloses at least one electromagnetic interference filter element except for a portion of the primary termination pads and the secondary termination pad. The VMEIF may be combined into either a multi-element electromagnetic interference filter or into a multiple input/output modular structure, as well as embedded within electrical circuitry.
