Introduction

Aluminum electrolytic capacitors belong to the larger category of electrical capacitors, which are devices that store energy in the form of an electrical field. LQS2W151MELB25 is a popular choice among aluminum electrolytic capacitors, as it is compact, has a long life, and is relatively inexpensive. This article will provide a detailed explanation of the application field and working principle of the LQS2W151MELB25.

Application Field

The LQS2W151MELB25 is a popular choice in power electronics and AC power circuit applications. This type of aluminum electrolytic capacitor can be used to store electric energy, reduce harmonic frequency, and smooth out pulses. It is also often used in frequency division, noise filtering, and DC blocking applications. This capacitor is also popular in automotive electrical systems, as its robust design is able to withstand the rigors of the road. Additionally, the LQS2W151MELB25 is suitable for industrial electronics and various military applications, such as power supplies and missiles.

Working Principle

The working principle of the LQS2W151MELB25 begins with a thin sheet of aluminum foil, which is sandwiched between two pieces of non-conductive paper. This is then submerged in a liquid electrolyte, which is primarily composed of a mixture of sulfuric acid and water. An electrical charge is applied to the aluminum foil, which causes a chemical reaction to take place. This reaction makes the liquid electrolyte form a thin film on the aluminum foil, which acts as the dielectric of the capacitor.When a positive voltage is applied to the positive terminal of the capacitor, positive ions move toward the negative terminal of the capacitor. At the same time, negative ions move towards the positive terminal. This movement of ions creates an electrical field, which in turn stores the electrical charge within the capacitor. When the voltage is removed, the ions will return to their original positions, allowing the electrical charge to be released. This discharge of electrical charge is what makes the LQS2W151MELB25 suitable for various applications.

Conclusion

The LQS2W151MELB25 aluminum electrolytic capacitor is a popular choice for various power electronics, AC power circuits, automotive electrical systems, industrial electronics, and military applications. Its compact size, long life-span, and low cost make it an attractive choice for many applications. Additionally, its working principle is simple yet effective, as electric charge is stored when a voltage is applied, and released when the voltage is removed.
