It is also used in electronic products that require fast reaction times such as switching applications.

UPS1E220MDD Operating Principle

The current flow in an aluminum electrolytic capacitor is based on the principles of electrolysis. When a direct current is applied, a slow electron migration occurs between the anode and the cathode of the capacitor, forming an electrolyte solution. The positive ions are attracted to the positive electrode, the anode, and the negative ions are attracted to the negative electrode, the cathode. This process forms a conducting layer on the surface of the anode, which allows the current to pass from the anode to the cathode. The capacitance is determined by the area and thickness of the anode and cathode layers.

As the current passes through the capacitor, electrical energy is stored. This stored energy can then be released when the capacitor is reverse biased. When the capacitor is reverse biased, the electrons present at the anode are repelled, causing them to travel to the cathode. This process creates a charge imbalance, which causes the capacitor to release current.

Conclusion

The UPS1E220MDD is an aluminum electrolytic capacitor which can be used in a variety of applications. It has a low ESR, low ESL, and high ripple current ratings, making it an ideal choice for applications requiring fast reaction times. It is also UL certified and RoHS compliant. Its operating principle is based on the principle of electrolysis, which allows the capacitor to store and then discharge electrical energy.
