Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a polarized capacitor whose anode electrode is made of a pure aluminum foil with an etched surface. The electrolyte, which covers the rough surface of the aluminum anode, is a chemical mixture of clear, colorless liquid or a paste. The second and the third electrodes are the cathode, which is made of a pure aluminum foil, or a metal film or particle-filled liquid. The electrolyte and the electrodes are separated by a dielectric oxide film that has been formed on the oxide-covered surface of the aluminum foil.

UUJ2C470MNQ1MS application field and working principle

The UUJ2C470MNQ1MS aluminum electrolytic capacitor is primarily used in applications that require a low-impedance and low-loss power supply such as power supplies for motor, light, thermoelectric elements and other electronic devices.

The working principle of the UUJ2C470MNQ1MS aluminum electrolytic capacitor is based on the electrical double layer. When voltage is applied to the capacitor, the electric double layer is formed on the dielectric oxide film which separates the anode and the cathode. This layer results in the formation of an electric field that generates electric charges on the capacitor plates, which induce an electric current between the anode and the cathode through the electrolyte. The electric current creates an electrostatic energy, which is stored in the capacitor.

The UUJ2C470MNQ1MS has a wide range of applications such as in radio frequency circuit filters and electric device transistors. It is also used in surge suppressors, over-voltage protector circuits and as an efficient energy storage capability. Due to its low impedance, it is also well suited for use in power supplies, electric motor controls and DC-DC converters.
