Presidio Components, Inc. - San Diego CA

International Classification:

H01G 435

US Classification:

361302, 361303

Abstract:

The size and placement of internal metallization areas as do collectively form each of two electrodes is improved in a typically discoidal feed-through ceramic filter capacitor having (i) multiple ceramic layers, (ii) a hole passing a wire that carries electrical signals which are to be filtered, (iii) metal lining the hole so as to make electrical contact with the wire, and (iv) an exterior metal band connected to ground. First internal metallization areas, each in the shape of a relatively smaller small-aperture disk, are centered about the bodys hole in contact with the metal lining, each area being upon one of the bodys multiple ceramic layers, the areas collectively serving as a first electrode of the capacitor. Second internal metallization areas, each in the shape of a relatively larger large-apertured disk also centered about the hole and upon one of the ceramic layers, make at their exterior edge surface electrical contact with the metal band, thereby to serve as a second electrode of the capacitor. The respective metallization areas of each electrode are both (i) spaced far apart by previous standards, and, preferably, (ii) are located upon alternating ceramic layers, making that any voltage breakdown path is necessarily both (i) long and with (ii) both radial and longitudinal components.

Assignee:

Presidio Components, Inc. - San Diego CA

International Classification:

H01G 435

US Classification:

304302, 361303

Abstract:

A feed-through capacitor has layers of dielectric material and a first hole that passes through the layers of dielectric material for receiving an electrical conductor connected to the filter capacitor. First, second and third electrodes are disposed between layers of the dielectric material and extend in a first direction substantially perpendicular to a centerline of the first hole. The third electrodes are disposed intermediate the first and second electrodes. Any one of the first, second and third electrodes is non-overlapping with any of another of the first, second and third electrodes in a direction substantially parallel to the centerline of the first hole. A filtering capacitor is formed substantially wholly by fringe-effect capacitance between the first and third electrodes, and a coupling capacitor is formed substantially wholly by fringe-effect capacitance between the second and third electrodes. The filtering and coupling are electrically connected in series.

Assignee:

Presidio Components, Inc. - San Diego CA

International Classification:

H01G 4005

US Classification:

361303, 3613061, 361311

Abstract:

A monolithic or essentially monolithic single layer capacitor with high structural strength and capacitance. Sheets of green-state ceramic dielectric material and ceramic/metal composite material are laminated together, diced into individual chips, and fired to sinter the ceramic together. The composite material may contain an amount of metal sufficient to render the composite conductive whereby the composite may be used for one or both electrodes and for mounting the capacitor. Alternatively, the composite material may contain an amount of metal insufficient to render the composite conductive but sufficient to act as seed points for an electroplating process wherein the composite is preferentially coated with conductive metal, the coated composite is mounted, and the coating provides an electrical connection to an internal electrode. Vertically-oriented surface mountable capacitors and hybrid capacitors are provided.
