Aluminum electrolytic capacitors are widely used in all kinds of electronic products with their stable performance and reasonable prices. Among them, the ESMQ451VSN221MP45S is a type of aluminum electrolytic capacitor. This paper will discuss its application field and the working principle.

Firstly, ESMQ451VSN221MP45S is mostly used in DC power supply. It enables direct current to slowly discharge and quickly charge in a short cycle. Therefore, it is especially suitable to be used in the DC power component of a transformer or a battery. In addition, it can be used to filter out the fluctuation in the output DC voltage of AC-DC power converters.

In addition, ESMQ451VSN221MP45S is also used in a variety of circuit designs. As a bypass capacitor, it can be used to supply power at specific frequencies, reduce electromagnetic interference, reduce the amount of noise, and correct low frequency pulse waveforms. As a coupling capacitor, it can be used to transmit the AC component of the signal waveform and block DC component, preventing the interference among different circuits.

Then, let’s discuss the working principle of the ESMQ451VSN221MP45S. As a type of aluminum electrolytic capacitor, it is composed of an aluminum oxide film, an anode made of aluminum plate and a cathode plate that is covered with a insulating paper. When the capacitor is connected to the power supply, the anode and the aluminum oxide film are subjected to the electric field, which is called the electric breakdown. The electric field causes the electrons to move and create current, generating a magnetic field. This magnetic field is amplified and causes the aluminum oxide film to break down, thus enabling the capacitor to complete the electric charging and discharging.

In conclusion, ESMQ451VSN221MP45S aluminum electrolytic capacitors are commonly used in DC power supplies and a variety of circuits. Its working principle is based on the electric breakdown and the generation of the magnetic field. It is easy to use and exhibit high performance, so it is a popular choice among electronic engineers.
