Abstract
Abstract The present invention is directed to a capacitor device and method of forming same, and more particularly to a monolithic ceramic capacitor incorporating an improved conductive termination arrangement providing a compliant connector for mechanically and electrically connecting the capacitor to a substrate, said termination arrangement providing increased resistance to damage to the capacitor as a result of differential coefficient of expansion between the capacitor and the substrate on which it is mounted.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
181 words
An electrical device adapted to exhibit an improved electrical and mechanical connection to a substrate, comprising a chip capacitor including, a ceramic dielectric body having upper and lower planar surfaces and opposed first and second spaced parallel end surfaces normal to said upper and lower surfaces, first and second electrical terminals formed on and substantially completely covering said end surfaces, first and second flexible connector tabs electrically and mechanically connected to said first and second terminals, respectively, said tabs including attachment portions affixed to said electrical terminals along connection lines adjacent the junction of said end surface and said upper surface, said tabs further including outwardly directed coplanar mounting portions, the area between said attachment portions and said mounting portions of said tabs including arcuate flexible portions, said arcuate flexible portions of said tabs being spaced from said end surfaces of said body in the area between said attachment portions and said lower surface of said dielectric body and further being spaced from surfaces of a substrate to which the mounting portions of the tabs electrically and mechanically connect in use.
