Abstract
A finished capacitor product and method in which the outer dielectric, protecting or encapsulating the basic inner capacitor structure, is improved in dielectric quality, relative to prior art and relative to the inner dielectric between plates. This improved outer dielectric has been experimentally demonstrated to provide improved electrical performance, including better signal handling performance, for the capacitor. This finding is contrary to prior art, which has attached great significance to the quality of the inner dielectric between capacitor plates, but has not attached great significance to the quality of the dielectric outside the capacitor plates.
