Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used electronic components in all electrical and electronic products because of their relatively large capacitance, low price and small volume. The 25YXG2200MEFC18X20 is a type of aluminum electrolytic capacitor. Its main features and working principle are introduced in this paper.

Application field

Aluminum electrolytic capacitors have a wide range of application fields. The 25YXG2200MEFC18X20 are mainly used in power supply filtering, power output device protect, LCD display and electric charge/discharge circuit. Taking A/V equipment, mobile phones, personal computers and digital cameras as examples, the 25YXG2200MEFC18X20 are used in A/V equipment for power supply filtering and output device protection, used in mobile phones for LCD display, and used in personal computers and digital cameras for electric charge/discharge circuit and so on.

Working principle

Aluminum electrolytic capacitors are composed of an anode made up of aluminum foil and a cathode made up of manganese dioxide. The anode is covered with a corrosion protective film to prevent the contact of the aluminum and the electrolyte, while the cathode is immersed in the electrolyte. When the capacitor is connected with the DC power supply, the electric field will be formed between the two electrodes, which enables the current to pass through the capacitor.

On the other hand, when the capacitor is connected with the AC power supply, current will be formed in the capacitor, so that the anode and the cathode are inversely charged and stored in the opposing state. The stored energy can then be released when the power supply voltage decreases. Subsequently, the capacitor will be able to keep the current flowing stably.

Conclusion

Aluminum electrolytic capacitors, such as the 25YXG2200MEFC18X20, are widely used in all kinds of electronic products due to their strong functions. They are mainly used in power supply filtering, power output device protect, LCD display and electric charge/discharge circuit. Their working principle is based on the electric field formed between the two electrodes and the current formed when connected with the power supply.
