ABSTRACT:
Capacitor material for use in forming capacitors, is disclosed. More specifically, the invention is directed to capacitors formed from this material that have one or more discrete electrodes (314), each electrode (314) being exposed to at least two thicknesses of dielectric material (300). These electrodes (314) are surrounded by wider insulative material (312) such that the material can be cut, or patterned into capacitors having specific values. A single electrode can form a small value capacitor while still providing a larger conductive area for attaching the capacitor to associated circuitry. The thin dielectric (310) can be a tunable material so that the capacitance can be varied with voltage. The tunability can be increased by adding thin electrodes that interact with direct current.
