UKT1E222MHD

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a variety of electrical applications because of their excellent characteristics, including large capacitances and high-energy density. UKT1E222MHD is one of the popular series of aluminum electrolytic capacitors that is mainly used in consumer electronics due to its small size and longer life.

Application Field

UKT1E222MHD aluminum electrolytic capacitors are mainly used in mobile phones, digital cameras, digital player, laptop computers, TV receivers and other consumer electronic devices. The device can handle large currents and store the energy for a long time. It is often used for filtering, decoupling, or smoothing of supply voltage between stages in the power supply. In addition, it can also be used for power supply\'s start and stop functions, improving the stability and reliability of the system.

Working Principle

An aluminum electrolytic capacitor consists of two electrodes: the anode and the cathode immersed in an electrolytic solution. The anode is formed from an aluminum foil, which is pre-etched to increase its surface area and make it suitable for high-capacitance performance. As for the cathode, it usually consists of aluminum foil and paper sheet separator. The anode and the separator are placed sandwich-like and rolled into a compact cylinder. Thus, when an electrical charge is applied to the aluminum electrolytic capacitor, an electric current is generated from the anode to the cathode and stored in the form of electrical energy.

When the electric energy stored in an aluminum electrolytic capacitor reaches its maximum, a reverse electric current is generated. This reverse electric current is called “dielectric breakdown”, which is the limiting factor of the device working as it causes leakage and potential failure. That’s why it is important to follow the manufacturer’s recommendations of the use of aluminum electrolytic capacitors.

Conclusion

Aluminum electrolytic capacitors are extremely useful devices in the field of electrical engineering. UKT1E222MHD is one of the popular version of aluminum electrolytic capacitors, which is mostly used for various applications such as filters, power supplies, and stability control. It can also be used for other applications such as high-capacitance performance, energy storage, and dielectric breakdown protection. However, it is important to follow the manufacturer’s recommendations of the use of aluminum electrolytic capacitors.
