The Influence of Working Electrolyte on the High-voltage(160 V) Wet Tantalum Capacitors

In this work,the influence of organism on breakdown voltage and conductance of electrolyte of wet tantalum capacitor was investigated.The results of the experiments indicated that proper organic agents inducted into the working electrolyte could be absorbed at the interface of the Ta_2O_5 dielectric film,and help to reduce the effective consistence and the charge of negative ion,so the broken-voltage of the working electrolyte could be increased.Through 1 000 h high temperature-loading experiment,the results showed the electrical characteristics of the 160 V/47 μF capacitors using the electrolytes are good.
