In daily life, it is often encountered that long-term use of wires leads to aging and cannot be used. Will the capacitor aluminum case
, which is a container for electricity, experience aging?
The working electrolyte of the capacitor aluminum shell uses weak acid/weak alkali salt as the electrolyte, water and organic solvent as the solvent, but it is still corrosive and corrosive to the anodic oxide film and rubber plug of the capacitor. In addition, the chemical reaction between the electrolyte salt and the solvent will occur over time. These phenomena will cause the deterioration of the electrical performance of the capacitor. Therefore, the capacitor aluminum case is also prone to aging.
The shortcomings of aluminum electrolytic capacitors limit its application in certain occasions. However, due to its high capacity and price advantage and other significant advantages, it is firmly in the competition with ceramic capacitors, film capacitors, and tantalum electrolytic capacitors. Land occupies more than 30% of the share. And with the development of power electronic technologies such as automotive electronics and frequency conversion technology, its proportion will have a significant upward trend.
