The capacitance range for this unit is from 18uF to 810uF. One of the most popular applications for this type of capacitor is in adjustable DC power supplies.

Application Field

The 400BXF18MT810X20 aluminum electrolytic capacitor is often used in power supplies to help regulate power levels. These capacitors can reduce current peaks, reduce line-to-ground noise, and filter out high-frequency switching signals. They are also used in medical equipment, digital audio amplifiers, and lighting control systems. The capacitor is used to store and release energy quickly, which allows for smoother current operation.

Working Principle

The operation of an electrolytic capacitor, such as the 400BXF18MT810X20, relies on the principle of electrolysis. The two aluminum electrodes are placed in a solution of electrolyte, which consists of a liquid and a chemical compound ionized into positive and negative ions. When a charge is applied to one of the electrodes, the positive ions are drawn to it and the negative ions are drawn to the other electrode. This process causes a separation in electrical charge, creating a capacitance between the two electrodes. The capacitance of the capacitor is determined by the amount of electrodes, their distance apart, and the type of electrolyte used.

The 400BXF18MT810X20 aluminum electrolytic capacitor uses a combination of design features to maximize capacitance and reduce power loss. The capacitance is controlled by the amount of electrode area, the distance between the electrodes, and the electrolyte level. The power loss of the capacitor is minimized by the use of a dielectric that is highly temperature stable, which prevents voltage drops over time. The capacitor is also designed to minimize ESR (equivalent series resistance) and ESL (equivalent series inductance).

Conclusion

The 400BXF18MT810X20 aluminum electrolytic capacitor is a widely used component that is designed for a variety of applications. Its operation relies on the principle of electrolysis, which creates a capacitance between two aluminum electrodes in an electrolyte solution. The capacitor is used to regulate power levels, reduce current peaks, reduce line-to-ground noise, and filter out high-frequency signals. The design features of this unit allow for maximum capacitance and minimal power loss, making it a valuable component for many different applications.
