Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are energy storage devices. They store energy in the form of an electrical current between two metal plates separated by an electrolytic fluid. Aluminum electrolytic capacitors store much more energy than regular capacitors, and are widely used in a variety of applications as they provide a larger capacitance range, higher current rating, and longer life cycle than other types of capacitors.

Aluminum electrolytic capacitors consist of two aluminum foil sheets separated by a paper dielectric material soaked in an electrolyte solution. The two aluminum sheet terminals are connected to the foil side of the electrolyte solution and the negative terminal is connected to the non-foil side. The application of a voltage causes an ionic layer to form on the exposed aluminum and electrolyte. The capacitors have a dielectric in the form of anhydrous and hydrous oxidation film. An uneven level of electrolyte and current flow are what cause the capacitor to work.

UVR2F470MHD: Application Field and Working Principle

UVR2F470MHD is a type of aluminum electrolytic capacitor that is predominantly used to provide a stable source of power to circuits and electronics. It’s a non-polarized capacitor which has low insulation resistance and is highly resistant to electrostatic shock and environmental changes. The UVR2F470MHD is a double-ended type aluminum electrolytic capacitor, meaning it has a common lead on both ends of the capacitor for electrical connections.

The UVR2F470MHD is designed for use in low-voltage, high current pulse discharge applications, such as in electronic, automotive and general instrumentation applications. The UVR2F470MHD is designed for applications with a working voltage of 0.5 – 50 VDC and a capacitance of 1 – 470 µF. The maximum surface temperature of the capacitor is rated at 70°C. UVR2F470MHD aluminum electrolytic capacitors are generally considered to be stable, reliable and cost effective.

The working principle of UVR2F470MHD aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. When a voltage is applied to the UVR2F470MHD capacitor, the current causes a layer of oxide film to form on the aluminum foil plates, which acts as the dielectric. The combination of the oxide film and the electrolyte make a solid-state capacitor. The capacitance of the capacitor is a result of the area of the aluminum foil, its thickness and the electroyte solution.

Conclusion

UVR2F470MHD aluminum electrolytic capacitors are widely used in DC high current applications. The capacitors are durable and cost-effective, and provide good electrical insulation, low insulation resistance and good temperature stability. UVR2F470MHD aluminum electrolytic capacitors work by forming an oxide film on the aluminum foil plates when a voltage is applied, and the combination of this oxide film and the electrolyte make a solid-state capacitor with a specified capacitance.
