Aluminum electrolytic capacitors are an essential part of the electronic industry. ELHS451VSN471MR45S capacitors are a commonly-used type of aluminum electrolytic capacitor used in many electronics, ranging from industrial equipment to automobiles. This article will discuss the application field and working principle of ELHS451VSN471MR45S aluminum electrolytic capacitors.

LS451VSN471MR45S aluminum electrolytic capacitors are mainly used in electronic products for power rectifier circuits (also known as filters) and the circuits that need a larger capacitance than that provided by general ceramic capacitors. They feature low impedance, stable temperature characteristics, good frequency characteristics, and a long life. With these characteristics, they are suitable for use in applications such as power supplies, voltage stabilization devices, and power amplifiers.

The working principle of aluminum electrolytic capacitors is based on two electrodes that are separated by an electrolyte. The two electrodes are aluminum and a layer of an oxide film. The anode electrode is formed by oxidizing the aluminum, forming an aluminum oxide layer that allows the current to pass through, resulting in a very high insulation resistance. The cathode is typically formed of a carbon film deposited on an aluminum layer.

When electric current passes through the component, the electric charge will be stored. This electric charge makes the oxide layer of the anode thicker, thus increasing the capacitance of the capacitor. In basic operation, when an AC voltage is applied, the oxide layer will expand and retract with the alternating current, enabling the capacitor to charge and discharge and thus store electric current. The electrolyte acts as an insulator, which allows the voltage potential to exist almost indefinitely, allowing the capacitor to function.

In summary, ELHS451VSN471MR45S aluminum electrolytic capacitors are commonly used in a wide range of electronic products, mainly used for power rectifier circuits and circuits requiring capacitors with higher capacitance than what ceramic capacitors can provide. They feature low impedance, stable temperature characteristics, good frequency characteristics, and a long life. The working principle is based on two electrodes that are separated by an electrolyte. When electric current passes through the component, the electric charge will be stored, enabling the capacitor to store electric current.
