Description
Elektrolytkondensator, insbesondere Tantalkondensator Die Erfindung betrifft Elektrolytkondensatoren, insbesondere Tantalkondensatoren, deren Elektrolyt als Depolarisator ein Kupfersalz enthält.Electrolytic capacitor, in particular tantalum capacitor The invention relates to electrolytic capacitors, in particular tantalum capacitors, their electrolyte contains a copper salt as a depolarizer.
Als Zusatzstoffe wurden bisher Ag,SO, und CuS04 für schwefelsäurehaltige Elektrolyte und Eisenchloride für chlorionenhaltige Elektrolyte verwendet.So far, Ag, SO and CuS04 have been used as additives for those containing sulfuric acid Electrolytes and iron chlorides used for electrolytes containing chlorine ions.
FeCl. oder FeCI.= in chlorionenhaltigem Elektrolyten haben den Nachteil, daß bei relativ niedriger Spannung ein Angriff auf das Dielektrikum Tantaloxyd erfolgt, der einen elektrischen Durchschlag zur Folge haben kann. Kondensatoren mit mehr als etwa 15 V Nennspannung sind daher kaum herstellbar.FeCl. or FeCl. = in electrolytes containing chlorine ions have the disadvantage that the dielectric tantalum oxide is attacked at a relatively low voltage, which can cause an electrical breakdown. Capacitors with more a nominal voltage of about 15 V can therefore hardly be produced.
Bei Verwendung von Ag2S0, bzw. CuSO4 in schwefelsaurer Lösung wird keine vollständige Beseitigung der Wechselspannungsabhängigkeit von Kapazität und Verlustfaktor erzielt, da bei der wegen der auch bei tieferen Temperaturen erforderlichen hohen Leitfähigkeit des Elektrolyten verwendeten hohen Säurekonzentration die Löslichkeit der Zusätze zu gering ist, um noch ausreichend depolarisierend zu wirken.When using Ag2S0 or CuSO4 in sulfuric acid solution does not completely eliminate the AC voltage dependency of capacitance and Loss factor achieved because of the necessary because of the lower temperatures high conductivity of the electrolyte, high acid concentration used the solubility of the additives is too small to have a sufficiently depolarizing effect.
Demgegenüber bringt die erfindungsgemäße Verwendung von CuCI._ als Depolarisator in chlorionenhaltiger Lösung für den Elektrolyten entscheidende Vorteile für den Elektrolytkondensator.In contrast, the inventive use of CuCI._ brings as Depolarizer in a solution containing chlorine ions for the electrolyte has decisive advantages for the electrolytic capacitor.
Das folgende Beispiel zeigt die Überlegenheit des CuCl,- haltigen
Elektrolyten.
