SOLID ELECTROLYTIC CAPACITOR

摘要

THE PRESENT INVENTION AIMS TO PROVIDE A CHIP-TYPE SOLID ELECTROLYTIC CAPACITOR OF LARGE CAPACITANCE AND LOW ESR. AN ELEMENT SECTION OF THE CAPACITOR IS COMPOSED OF AN ANODE OXIDE FILM LAYER WHICH FUNCTIONS AS A DIELECTRIC, A SOLID ELECTROLYTE LAYER INCLUDING CONDUCTIVE POLYMER AND A CATHODE CONDUCTIVE BODY, WHICH ARE STACKED ON A METALLIC ELECTRODE. A PLURALITY OF FLAT CAPACITOR ELEMENTS WITH THE ELEMENT SECTION AND AN ANODE PULLING-OUT SECTION (4) ARE STACKED, AND A LAMINATED UNIT IS PRODUCED WHERE THE CATHODE CONDUCTIVE LAYER AND THE ANODE PULLING-OUT SECTION (4) OF THE FLAT CAPACITOR ELEMENTS ARE CONNECTED TO A SINGLE METALLIC TERMINAL MEMBER EACH. THE SOLID ELECTROLYTIC CAPACITOR OF THE PRESENT INVENTION HAS AT LEAST TWO LAMINATED UNITS PLACED PARALLEL TO EACH OTHER, AND CONNECTED TO A TRANSVERSELY DISPOSED COMB TERMINAL. THE CONSTRUCTION PRESENTED BY THE PRESENT INVENTION ACHIEVES A SOLID ELECTROLYTIC CAPACITOR OF A LARGE CAPACITANCE AND A LOW ESR WITHOUT EXPANDING ITS MOUNTING SURFACE AREA. (FIGURE 1)
