Introduction

Aluminum electrolytic capacitors are one of the most common capacitor types in electronics, used in almost every electrical device from power supply units to mobile phones. The 400LSW2200MNB77X101 is an industrial grade aluminum electrolytic capacitor which guarantees ultra-low ESR and high ripple current handling capability. It has a long lifespan and exceptional performance in harsh working conditions. This article will discuss the application field of the 400LSW2200MNB77X101 and its working principle.

Application Field

The high performance characteristics of the 400LSW2200MNB77X101 make it suitable for various applications. It is a common choice for users of industrial-grade switch mode power supplies, where its long life and high ripple current performance make it indispensable. Its long life and stress-free operation mean that it can also be used in high power frequency equipment, such as inverters, UPS systems, motor drives and welding equipment, to guarantee stable operation. It can also be used in renewable energy storage systems such as wind turbines, solar power plants and water turbines, thanks to its reliable operation in fluctuating input voltages. The 400LSW2200MNB77X101 is also used in military systems where its -55°C to +105°C temperature range makes it suitable. Finally, it is also well suited for automotive applications, such as starter battery management systems and charging systems, thanks to its 3000h endurance parameters which guarantee long-term reliability.

Working Principle

The 400LSW2200MNB77X101 is an aluminum electrolytic capacitor. It works on the same principle as all other electrolytic capacitors, whereby an anode material such as aluminum is separated by an electrolyte, usually in gel or oil form, between a positive and negative capacitor plate. When an electrical current is applied, the current separates the anode material into its component ions, allowing current to flow. This creates an electric field within the capacitor, allowing it to store charge. As the charge builds up, the field gets stronger, and the capacitor plates become more oppositely charged. This creates the capacitor’s electrical charge, and the amount of charge stored is determined by the amount of current and voltage applied.

Conclusion

The 400LSW2200MNB77X101 is an industrial grade aluminum electrolytic capacitor providing excellent performance in harsh and demanding applications. Its ultra-low ESR and high ripple current handling capability make it a great choice for industrial-grade switch mode power supplies, as well as inverter, UPS, and motor drives. Its -55°C to +105°C temperature range and 3000h endurance parameters also make it suitable for military systems and automotive applications. Its working principle is based on the same concept as all other electrolytic capacitors, whereby an anode material such as aluminum is separated by an electrolyte between a positive and negative capacitor plate.
