Nonpolar feed-through capacitor
Abstract
Abstract A NONPOLAR FEED-THROUGH SOLID ELECTROLYTE CAPACITOR IS PROVIDED BY FORMING A FEED-THROUGH SOLID ELECTROLYTE CAPACITOR WITHIN THE APERTURE OF ANOTHER SOLID ELECTROLYTE CAPACITOR OF TUBULAR CONFIGURATION, ELECTRICALLY CONNECTING THEIR RESPECTIVE CATHODES AND CONNECTING THE ANODE OF THE OUTER CAPACITOR TO A CASING. THE CAPACITOR ASSEMBLY OFFERS A LOW LINE-TO-GROUND IMPEDANCE PATH FOR HIGH FREQUENCY SIGNALS AND NOISE AND A LOW FREQUENCY LOW IMPEDANCE PATH THROUGH THE FEED-THROUGH CAPACITOR. THE LOW LINE-TO-GROUND IMPEDANCE PATH FOR HIGH FREQUENCY SIGNALS IS IMPROVED BY THE ADDITION OF CIRCULAR FEED-THROUGH CERAMIC CAPACITORS AT EACH TERMINAL. THE FEEDTHROUGH CERAMIC CAPACITORS PROVIDE IMPROVED FREQUENCY RESPONSE TOGETHER WITH HERMETIC END SEALING OF THE CASE.
