STUDY ON FAILURE MECHANISM OF LIQUID TANTALUM ELECTROLYTIC CAPACITORS |
| |
| Abstract: | The Failure mechanism of liquid tantalum electrolytic capacitors was discussed by means of electronic microscopic analysis.The result shows that the ultimate factor causing failure is macroscopic and microscopic flaws in the dielectric film.According to this theory,adopting complete sealing structure,choosing better materials and manufacture process and reasonably using the products are the important means to enhance the reliability of liquid Tantalum electrolytic capacitors. |
