1 Failure modes and factors failure of aluminum electrolytic capacitors The positive and negative lead-out electrodes and shells of aluminum electrolytic capacitors are made of high-purity aluminum. The medium of aluminum electrolytic capacitors is an aluminum oxide film formed on the surface of the positive electrode. The real negative electrode is the electrolyte, which is equivalent [...]
Application development of aluminum electrolytic capacitors The global aluminum electrolytic capacitor supply market is becoming more and more mature, mainly in Japan, China, Taiwan, and South Korea. Judging from the overall competition pattern of the industry in recent years, the production volume of electrolytic capacitors in Japan has gradually shrunk, replaced by Korean companies, Taiwanese companies, [...]
The role of electrolytic capacitors in the circuit 1. filtering In the power supply circuit, the rectifier circuit converts the alternating current into a pulsating direct current, and after the rectifying circuit, a large-capacity electrolytic capacitor is connected, and the rectified pulsating DC voltage is changed into a relatively stable direct current by utilizing its charging [...]
