SMD electrolytic capacitors are used as input filtering and smoothing components. Once a problem occurs, it may directly cause circuit failure. Its quality and stability directly affect the reliability of the power supply.
Power supply products are one of the important application areas of SMD electrolytic capacitors, and its reliability has always been the most concerned issue. So, how to improve the reliability of SMD electrolytic capacitors in power supply?
SMD electrolytic capacitors are used as input filtering and smoothing components. Once a problem occurs, it may directly lead to circuit failure. Its quality and stability directly affect the reliability of the power supply. First, it has to be mentioned that its life is special. Concerned about reliability issues. The main factor affecting its life is its high temperature resistance, because the higher the temperature, the longer it will be, and the shorter its life. Therefore, the chip electrolytic capacitor in the power supply product must be carefully selected to consider its high temperature resistance.
In addition, the ripple current is also an important characteristic that affects the reliability of the chip electrolytic capacitor in the power supply. The power consumption generated on the ESR causes the chip electrolytic capacitor to generate heat, thereby shortening the service life and reducing the stability. This is also a key feature of the reliability of chip electrolytic capacitors in power products. Http://news.chinawj.com.cn
