Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various applications due to their low cost and typically high capacitance. They are also characterized by their ability to store electrical energy in the form of an electric field. The basic working principle of aluminum electrolytic capacitors is based on an electrochemical reaction that takes place between a solid electrolyte and two electrodes – the anode and the cathode.

UVR0J223MHA Application Field and Working Principle

UVR0J223MHA aluminum electrolytic capacitors are non-polarized, low-profile, versatile capacitors designed for a variety of applications. The device features an extended temperature range from -55°C up to +125°C, a wide capacitance range from 0.47μF to 22μF, high ripple current ratings up to 1.4A, and low equivalent series resistance. UVR0J223MHA capacitors are based on a standard aluminum electrolytic construction with a series of plate electrodes covered by a solid electrolyte and encased in a rugged epoxy enclosure.

At the core of the UVR0J223MHA aluminum electrolytic capacitor is a solid electrolyte material composed of an oxidized aluminum anode layer with a dielectric oxide layer, and a conductive cathode layer. When an electrical potential is applied to the device, current passes through the solid electrolyte and toward the conductive cathode layer. The electric current forces an ionic conduction between the two layers, resulting in the formation of an electric field between them and the accumulation of electrical energy.

The UVR0J223MHA capacitors are non-polarized, meaning they can operate with either a positive or negative polarity applied to the leads. This allows the device to be used in applications where two-way polarity may occur, such as AC to DC power conversion, switching power supplies, and electronic timing applications. As the device features low equivalent series resistance and a high operating temperature range, UVR0J223MHA capacitors are suitable for applications that may require high ripple current levels and/or high temperature operation.

In summary, aluminum electrolytic capacitors are devices that utilize an electrochemical reaction to store electrical energy in the form of an electric field. The UVR0J223MHA capacitors are non-polarized, low-profile devices specifically designed for a variety of applications, featuring a wide operating temperature range, a wide capacitance range, and high ripple current ratings. They are suitable for many applications that require high-temperature operation and/or high ripple current levels.
