Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, sometimes referred to as electrolytic polymer capacitors (EPCs), are a type of capacitor that uses an electrolyte composed of an organic solvent and a metal oxide or an aluminum oxide/polymer film as a dielectric. The metal oxide or inorganic layer provides the electrical insulation and the aluminum oxide layer is the electrode whose electrical properties determine the capacitor\'s overall characteristics.

The particular UVZ2W100MHH capacitor belongs to the family of aluminum electrolytic capacitors and it has a broad range of applications in circuits such as high voltage power supplies; high-frequency RF amplifiers; UPS systems; electric motors; and industrial equipment.

Working Principle:

The UVZ2W100MHH capacitor consists of two aluminum foil electrodes with an oxide layer in between. The oxide layer acts as the dielectric and provides the electrical insulation necessary to allow the capacitor to function. When a voltage is applied across the two electrodes, an electric field is generated between them. This electric field causes electrons and ions to be forced towards the opposite electrodes, resulting in a current flow.

The electric current produces an electrochemical double layer at the interface between the two electrodes and the electrolyte solution. The electrochemical double layer acts as an insulating material that prevents further ion movement and limits the flow of current. This current-limiting effect is what gives the capacitor its capacitance.

The capacitor\'s capacitance is determined by its geometry and materials. The UVZ2W100MHH has an aluminum oxide/polymer dielectric, which provides a higher capacitance density while maintaining excellent performance over a wide temperature range.

In summary, the UVZ2W100MHH is an aluminum electrolytic capacitor specifically designed to handle high-frequency, high-voltage applications. Its extended temperature range and voltage rating makes it suitable for a variety of applications, including telecommunication systems, high-voltage power supplies, inverters and converters, and industrial traction vehicles.
