Also, it is often applied in power supply circuit of communication equipment, switch power supply and so on, providing DC connection and absorption of switching ripple. Its application can also be seen in personal computer and laptop motherboard, providing the necessary protective capacity for the CPU.

Working principle of UPA1C471MPD1TD model aluminum electrolytic capacitors:

Aluminum electrolytic capacitors are a type of capacitor consisting of an anode made of aluminum, a cathode made of aluminum sheet treated by chemical deposition, a dielectric material composed of solidified electrolyte, and a shell made of high intensity plastic. When in use, the two electrodes of the aluminum foil are first coated with the insulating film of the electrolyte, and then the electrolyte is solidified to form the dielectric layer. The structure is completed, and it can be used as a capacitance element.

The current applied to the UPA1C471MPD1TD aluminum electrolytic capacitor flows through the anode, electrolyte and cathode, before finally connecting to the load. When the load current passes, current will pass through the cathode layer to the surrounding electrolyte, and diffuse through the electrolyte to the anode. Due to the action of the diffusion capacitance effect or the potential barrier effect of the electrolyte, a reverse leakage current is generated, which performs buffering and decoupling functions.
