Aluminum Electrolytic Capacitor Application Field and Working Principle

Electrolytic capacitors are a type of capacitors featuring very high capacitance values in a very small size. They are widely used in a variety of different applications, ranging from consumer electronics to automotive and aerospace industries. Aluminum electrolytic capacitors are usually the preferred type of electrolytic capacitor due to their robustness and ability to handle big voltage differences. In this article, we will discuss the application field and working principle of an aluminum electrolytic capacitor with a capacitance of 400MXY150MEFC20X45.

Application Field of 400MXY150MEFC20X45

The aluminum electrolytic capacitor 400MXY150MEFC20X45 can be used in a variety of applications. It is used mainly in switch-mode power supplies since it features robustness and a relatively high capacitance. It can also be used in other high-power applications such as electric vehicles and renewable energy storage. Furthermore, this particular type of capacitor is often used in communication systems, as well as in audio power amplifiers and other sound equipment.

Working Principle of 400MXY150MEFC20X45

Aluminum electrolytic capacitors are composed of two electrodes made of aluminum foil, which are covered with a thin layer of anodic oxide. This oxide layer creates the insulation between the two electrodes. The aluminum foil is then submerged in an electrolyte solution, which is a weak acid.When the voltage across the capacitor increases, the electrolyte releases ions which bridge the gap between the two electrodes, allowing for more current to pass across the capacitor. This process is known as “Faradaic conduction”. As the voltage decreases, the electrolyte solution absorbs the released ions, and the capacitor discharges.Due to the electrolytic capacitor’s high capacitance and the ability to handle big voltage differences, it is known as a ‘polarized capacitor’, meaning that special attention must be taken when choosing the polarity of its connections during installation.

Conclusion

The aluminum electrolytic capacitor 400MXY150MEFC20X45 is widely used in a variety of applications, such as switch-mode power supplies, electric vehicles, communication systems, audio power amplifiers, and other sound equipment. It is a polarized capacitor, meaning that the polarity of the connections must be taken into consideration when installing the capacitor. Its working principle relies on Faradaic conduction, in which ions are released from the electrolyte solution in order to bridge the gap between the two electrodes, allowing for a high capacitance and big voltage differences to be handled.
