Aluminum electrolytic capacitors are widely used in various industries due to their low cost and excellent performance. The UST1H2R2MDD1TE is a member of the aluminum electrolytic capacitor family. This article will discuss the application fields of UST1H2R2MDD1TE and its operating principle.

Used for power supplies, timers used in clocks and watches, electric motor controls, and various other devices, UST1H2R2MDD1TE capacitors are mainly used for rectifier power supply filter circuits, DC-DC circuit filter circuits, signal-to-noise improvement circuits, and timing circuits. Additionally, it is used for energy storage in various circuit applications or voltage regulators, as well as automatic control circuits, by performing a "time constant" role.

The operating principle of the UST1H2R2MDD1TE is based on Faraday\'s law. This law states that when an electric current flows through a conductor in a magnetic field, a force is exerted on the conductor. Since the conductor is generally composed of two plates separated by an insulator, when current is applied to the plates, electrical energy is stored in a capacitive field. Consequently, a voltage difference appears across the plates, and after the current is stopped, the plates remain charged.

An electric double layer is formed on the surface of the aluminum electrolyte in the capacitor when voltage is applied, and electrons are stored in the electric double layer. The quantity of electric charge stored by the electric double layer is proportional to the applied voltage, so a linear relationship between charging current and storage charge is formed. Thus, the energy stored in the capacitor depends on the magnitude of the electric double layer. Besides, the capacitance formed by the electric double layer is represented by the dielectric constant of the electrolyte, and the capacitance of the capacitor can be calculated by using the following formula: C=K*A/D, where C stands for capacitance, K for dielectric constant, A for area, and D for dielectric.

To sum up, the UST1H2R2MDD1TE from the aluminum electrolytic capacitor family is mainly used for power supply filter circuits, DC-DC circuits, signal-to-noise improvement circuits, and timing circuits. Its main operating principle is based on Faraday\'s law, which states that when a current flows through a conductor in a magnetic field, a force is exerted on the conductor and an electric double layer is formed on the surface of the aluminum electrolyte in the capacitor when voltage is applied, and electrons are stored in the electric double layer. As such, the energy stored in the capacitor depends on the magnitude of the electric double layer, which can be calculated by using the formula C=K*A/D.
