Abstract
Abstract The possibility of shorting through potential failure paths at high voltage in a monolithic ceramic capacitor is reduced by inclusion of floating electrodes alternately spaced between sets of capacitor plates which are deposited on the same surface of ceramic layers in a ceramic stack.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
164 words
A high voltage monolithic ceramic capacitor comprising a monolithic stack of a plurality of sintered-together ceramic layers of equal length and width; a first conductive coating on a planar surface of a layer of said stack, said first coating egressing at opposite ends of said stack and divided by a ceramic margin as to form two separate conductive surfaces; a second conducting coating of substantially the same width as said first coating on another planar surface of a layer of said stack with a ceramic margin extending perimetrically around said second coating to form a floating electrode bridging said margin of said first coating; said second coating being disposed to said first coating as to form a ceramic surface between conducting surfaces; a plurality of said first and second coatings alternately disposed in said stack; and the top and bottom of said stack being layers of insulative ceramic, said floating electrodes forming an interface with the inside surface of said top and bottom layers.
Claim 2
Dependent Claim
164 words
A high voltage monolithic ceramic capacitor comprising a monolithic stack of a plurality of sintered-together ceramic layers of equal length and width; a first conductive coating on a planar surface of a layer of said stack, said first coating egressing at opposite ends of said stack and divided by a ceramic margin as to form two separate conductive surfaces; a second conducting coating of substantially the same width as said first coating on another planar surface of a layer of said stack with a ceramic margin extending perimetrically around said second coating to form a floating electrode bridging said margin of said first coating; said second coating being disposed to said first coating as to form a ceramic surface between conducting surfaces; a plurality of said first and second coatings alternately disposed in said stack; and the top and bottom of said stack being layers of insulative ceramic, said floating electrodes forming an interface with the inside surface of said top and bottom layers.
Claim 3
Dependent Claim
49 words
The capacitor of claim 1 wherein conductive plates provide electrical contact with said first conductive coatings which egress from said opposite ends of said capacitor, said plates being fixed in planes substantially perpendicular to the plane of said conductive coatings; and conductive leads making electrical contact with said plates.
