Introduction

Aluminum electrolytic capacitors are well-known in the electronics industry for their reliability and performance capabilities in applications needing capacitors. This article will discuss the application field and working principle of one specific type of aluminum electrolytic capacitor, the WBR2000-35A.

Overview of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are composed of an anode aluminum foil, cathode foil, electrolyte, separator (paper), and a tank. When the device is activated, the electrolyte is ionized, forming charged ions on the anode and cathode. This ionization creates an electric field across the surfaces of the anode and cathode, creating the effect of a capacitor between the two.They offer relatively large capacitance values for a given physical size, making them an attractive choice for most applications. Additionally, aluminum electrolytic capacitors possess excellent self-healing properties, which help to maintain good capacitance performance over the life of the device.

WBR2000-35A Application Field and Working Principle

The WBR2000-35A is a special type of aluminum electrolytic capacitor specifically designed for computing applications. Specifically, it is designed for use in computers, where it is used to store energy and provide peak current.The WBR2000-35A is an axial-leaded, cylindrical capacitor rated for 350VDC. The capacitance value of the device is 2000µF, and the capacitor has a temperature range of -40°C to +85°C.The capacitance of the WBR2000-35A is provided by polarizing an anode-cathode stack with an electrolyte. When the electrolyte is ionized, an electric field is generated between the anode and cathode, producing an electric potential. This electric potential is used to store energy, as well as provide peak current.The main advantage of the WBR2000-35A capacitor is its high capacitance – which provides abundant energy storage – and its low ESR (equivalent series resistance). This allows for efficient current transfer and lower power loss in applications requiring peak current. Additionally, the device is rated for 350VDC, allowing it to be used for high voltage applications, such as computer motherboards.

Conclusion

In conclusion, the WBR2000-35A is a special type of aluminum electrolytic capacitor designed for use in computing applications. It offers high capacitance and low ESR, allowing it to efficiently store energy and provide peak current. It also has a high voltage rating, making it suitable for use in high voltage applications.
