Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are non-polarized capacitors with the highest capacitance compared to other kinds of capacitors. They are widely used in power supplies, amplifiers, and many other electronic circuits. This article introduces the application field and working principle of the ELXY350ETC121MH12D aluminum electrolytic capacitor.

Application Field

The ELXY350ETC121MH12D aluminum electrolytic capacitor is mainly used in high voltage, high frequency circuits and power factor correction circuits requiring high capacitance. It is also suitable for switching power supplies, general and low frequency rectifier filters, automotive computers, switching power supplies, electric spraying equipment, ballast circuits, and medium-voltage DC drive circuits. Its application field is vast and its usage is important in many electronic circuits.

Working Principle

An ELXY350ETC121MH12D aluminum electrolytic capacitor consists of two parallel plates that are separated by an electrolyte-soaked paper. The two plates are made of aluminum foil and the electrolyte is a mixture of two liquid components. When a voltage is applied, a certain amount of current passes through the capacitor, forming a relatively stable electric field in the space between the two plates. This field then generates a certain amount of capacitance. The capacitance increases with the increase of the voltage.

The voltage is always limited by the electrolyte. The electrolyte not only serves as an electrically conducting medium, but also prevents excessive current passing through the capacitor. When the voltage is too high, the electrolyte will boil and dissipate a portion of the current, so as to maintain the safety of the circuit. That is why aluminum electrolytic capacitors are commonly used in high voltage and high frequency circuits.

In addition, the ELXY350ETC121MH12D aluminum electrolytic capacitor has a self-healing function. This function allows any small short circuits or damages inside the capacitor to be slowly repaired over time automatically.

Conclusion

To sum up, the ELXY350ETC121MH12D aluminum electrolytic capacitor is mainly used in high voltage and high frequency circuits and power factor correction circuits requiring high capacitance. It has a working principle involving two parallel-plate electrodes, with the electrolyte as the electrically conducting medium and forming an electric field when a voltage is applied. It also has a self-healing function and plays an important role in many electronic circuits.
