Aluminum Electrolytic Capacitors: UUH1V471MNQ1MS Application Field and Working Principle

Aluminum electrolytic capacitors are essential electronic components used in a wide variety of devices and systems. The UUH1V471MNQ1MS aluminum electrolytic capacitor stands out for its low ESR and high capacitance of 470uf. In this article, we explore the UUH1V471MNQ1MS application field and working principle.

UUH1V471MNQ1MS Application Field

The UUH1V471MNQ1MS capacitor’s main application field is filter and decoupling in power electronics. It is a highly reliable and stable capacitor, used in areas where AC/DC filtering is essential, such as in the power supply of computer systems, LED lighting, and household appliances.It is also used in medical equipment, automotive systems, and audio-visual equipment. In these systems, the capacitor’s low ESR and high capacitance ensure a reliable power supply. Also, it has low self-inductance, which makes it suitable for high frequency DC/DC converters.

Working Principle

The UUH1V471MNQ1MS aluminum electrolytic capacitor works on the principle of electrolysis. It consists of an aluminum oxide film or dielectric, which is kept in a rolled up or folded configuration. This is followed by two electrodes, one of which is typically made of aluminum and the other of a conductive material, such as conductive plastic, tin, stainless steel, or copper.When the capacitor is connected to a power supply, the oxide film acts as an insulator, creating an electric field between the two electrodes. This field causes electrons to move from the negative electrode to the positive electrode, resulting in an electric current across the capacitor. The electric current then creates a magnetic field, which in turn produces a voltage across the capacitor.The oxide film and the metal plates act as a dielectric, meaning that they allow current to flow but constrain the amount of electric energy that passes through them. This electric energy is stored in the capacitor, which is then used to produce a current in the connected circuit.

Conclusion

The UUH1V471MNQ1MS aluminum electrolytic capacitor is a versatile and reliable component, ideal for applications in filter and decoupling in power electronics. Its low ESR and high capacitance makes it suitable for DC/DC converters. Its working principle is based on electrolysis, where the oxide film and the metal plates act as a dielectric, allowing current to flow while constraining the amount of electric energy that passes through them.
