Reduce the Leakage Current of High Voltage Polymer Ta Electrolyte Capacitors

Abstract:

The leakage currents of high nominal voltage conductive polymer tantalum (Ta) electrolytic capacitors are the difficulties in the research and development processing. The optimized and improved forming technical of increasing current density with the voltage rising was used in the present paper, and silane coupling agent has been used to the dielectric surface of the electrode body before polymerization, and conductive slurry was used to forming the cathode electrolyte of capacitors. Low leakage currents and high breakdown voltage have been tested; otherwise, the endurance capabilities of reverse voltage have prodigious enhanced.
