Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used as a key component in various electronic circuits. This type of capacitor consists of two aluminum foil electrodes with a thin insulating membrane in between known as the dielectric. The capacitance, and hence capacitive reactance, is determined by the amount of area the two electrodes have.The UPA1E222MHD is a series of radial leaded aluminum electrolytic capacitors. This type of capacitor offers high capacitances, higher leakage current than conventional electrolytic capacitors and longer life. Furthermore, it is suitable for high temperature (125°C) and it has a narrow temperature range (20°C − 85°C).The UPA1E222MHD capacitors are mainly used in industrial, telecommunication, display, and electronic equipment. It can be used, for example, in DC power circuits, switching circuits, signal circuits, protection circuits, smoothing circuits, and oscillator circuits.

Working Principle of UPA1E222MHD Capacitor

The UPA1E222MHD capacitor is a non-polar aluminum electrolytic capacitor. It is designed with an insulated paper wrapped on one end, while the annular portion of the capacitor is constructed of an aluminum foil, a non-oxide paper separator and a lid. These components are soldered tightly together.The working principle of this aluminum electrolytic capacitor is based on the dielectric theory. When a voltage is applied to the capacitor, the liquid electrolyte will be polarized, allowing an electric current to flow from anode to cathode. In addition, the breakdown voltage of the capacitor is determined by the current passing through it and the maximum voltage range it can withstand.At high temperatures, the amount of electricity the capacitor is able to store is reduced significantly due to a decrease in the leakage current as well as the decrease in capacitance. This problem is caused by the increase in temperature, which expands the separation of the electrodes, allowing less electric current to flow from anode to cathode.

Conclusion

The UPA1E222MHD is a radial leaded aluminum electrolytic capacitor, which is obviously part of the Aluminum Electrolytic Capacitors family. It is widely used in industrial, telecommunication, display, and electronic equipment due to its high capacitances, and low leakage current, making them ideal for DC power, switching, and signal circuits. Its working principle is based on the dielectric theory, where the electrolyte is polarized when a voltage is applied, and the breakdown voltage is determined by the current passing through it.
