IMPROVED HIGH VOLTAGE CAPACITORS

摘要

ABSTRACR IMPROVRD HIGH VOITAGE CAPACTTIDRS A CAPACITOR INCLUDES A CERAMIC CAPACITOR BODY HAVING OPPOSITE ENDS AND COMPRISED OF A PLURALITY OF ELECTRODE LAYERS AND DIELECTRIC LAYERS AND FIRST AND SECOND EXTERNAL TERMINAL$ ATTACHED TO THE CERAMIC CAPACITOR BODY. THE INTERNAL ACTIVE ELECTRODES WITHIN THE CERARNIC CAPACITOR BODY ARE CONFIGURED IN AN ALTERNATING MANNER. INTERNAL ELECTRODE SHIELDS WITHIN THE CERARNIC CAPACITOR BODY ARE USED TO ASSIST IN PROVIDING RESISTANCE TO ARE-OVER. THE SHIELDS CAN INCLUDE A TOP INTERNAL ELECTRODE SHIELD AND AN OPPOSITE BOTTOM INTERNAL ELECTRODE SHIELD WHEREIN THE TOP INTERNAL ELECTRODE SHIELD AND THE OPPOSITE BOTTOM INTERNAL ELECTRODE 10 SHIELD ARE ON OPPOSITE SIDES OF THE PLURALITY OF INTERNAL ACTIVE ELECTRODES AND EACH INTERNAL ELECTRODE SHIELD EXTENDS INWARDLY TO OR BEYOND A CORRESPONDING EXTERNAL TERNFINAL TO THEREBY PROVIDE SHIELDING. SIDE SHIELDS ARE USED. THE CAPACITOR PROVIDES IMPROVED RESISTANCE TO ARC-OVER, HIGH VOLTAGE BREAKDOWN IN AIR, AND ALLOWS FOR SMALL CASE SIZE.
