Introduction
Aluminum electrolytic capacitors are a kind of large-capacity electrolytic capacitors which are widely used in electronic circuits or electronic equipment. The EKMH401VNN181MQ35T is a type of aluminum electrolytic capacitor, so this article will focus on the application field and working principle of this kind of capacitor.
Application Field
The application field of the EKMH401VNN181MQ35T is quite extensive, and the applications of aluminum electrolytic capacitors are mainly reflected in the aspect of power supply filtering seeking stable working voltages. Generally speaking, aluminum electrolytic capacitors are used to store energy. In practical application, they could shrink the ripple current of the line, adjust the amplitude and shift the phase of AC waveform, and provide the interference in a stabilization circuit. Besides, aluminum electrolytic capacitors are also widely used in the power factor compensation and charge&discharge circuits.
Working Principle
The capacitance of the aluminum electrolytic capacitor is formed by the combination of the electrolyte and two pieces of aluminum foil (anode and cathode). The aluminum foil of anode is dissolved by electrochemical oxidation to form very thin oxide film. This oxide film is an important dielectric medium which forms the electric capacity and determines the life of capacitor. In short, its working principle depends on the following two main theories:
- The first law of electrolytic capacitors: electrochemical oxidation forms dielectric films on the surface of aluminum foils.
- The second law of electrolytic capacitors: capacitance is determined by the thickness and quality of dielectric films.
To be specific, when the DC voltage is applied to an aluminum electrolytic capacitor, the surface of the anodic aluminum foil produces an oxide film. This oxide film is equivalent to a dielectric film with a large dielectric constant which is the capacitance of the capacitor. A part of the electrolyte molecules are adsorbed on the surface of the oxide film. Then they form a medium that enhances the electrical properties between the two electrodes. Therefore, when a current flows through the capacitor, electrochemical oxidation and ionization occur between the two electrodes.
Conclusion
In conclusion, the aluminum electrolytic capacitors, such as the EKMH401VNN181MQ35T, have found wide application in many electronic circuits and are popular in many fields. Its working principle is based on two main theories. Meanwhile, the capacitance formed by the combination of the electrolyte and two pieces of aluminum foil (anode and cathode) is the point that aluminum electrolytic capacitors are mainly used for storing energy.
