Aluminum Electrolytic Capacitors

The UVR1E222MHD is an aluminum electrolytic capacitor, a type of capacitor made with aluminum and containing electrolytic fluids in order to achieve increased capacitance ratings over other types of capacitors. Aluminum electrolytic capacitors have wide range of applications and have the ability to store large amounts of energy.

Application Field

Aluminum electrolytic capacitors are used in a wide range of electronics devices and systems. In audio loudspeakers, they are important components that provide power and enable the delivery of high-quality audio. They are also used in computers, LCD televisions, power supplies, medical machines, and in the manufacture of electronic components. They are most commonly used in applications where high capacitance and low leakage current are required.

Working Principle

Aluminum electrolytic capacitors are made by sandwiching a thin layer of aluminum oxide between two aluminum electrodes. The incorporated electrolytic fluid serves as an ionic medium and enables the capacitor to store more energy than regular capacitors. When a positive voltage is applied to the positive terminal of the capacitor, positive ions from the electrolytic fluid are attracted to the negative terminal, generating an electric field. This electric field causes the negative terminal to be charged while the negative ions are attracted to the positive terminal, thus increasing the capacitance. As a result, an aluminum electrolytic capacitor can be used as a storage device.

Aluminum electrolytic capacitors have a large capacitance for their size and can handle higher voltages and higher temperatures than other types of capacitors. This makes them ideal for applications where rapid charging and discharging are essential, such as power supplies and motors. However, standard aluminum electrolytic capacitors have low reliability, low working efficiency, and are prone to wear caused by electrolytic fluid leakage over time. For these reasons, other types of capacitors such as film capacitors, ceramic capacitors, and tantalum electrolytic capacitors are favored in some applications.

The UVR1E222MHD is an aluminum electrolytic capacitor with a maximum operating temperature of 105°C, a temperature coefficient of -20%, and a capacitance of 2200μF. This capacitor is primarily used in applications such as power supplies, motors, and medical machines, where high capacitance and high temperature resistance are needed.

The UVR1E222MHD is a reliable capacitance solution that offers a high degree of energy storage, a wide temperature range, and improved performance over other types of capacitors. It is especially well-suited for applications where reliability, stability, and low leakage current are a priority.
