What is the role of SMD aluminum electrolytic capacitors? What are the main uses?

SMD aluminum electrolyte capacitors are one of the most common capacitors on today's boards. In fact, other types of chip electrolytic capacitors, such as aluminum solid polymer capacitors, are manufactured in a similar way, except that the material used in the cathode is not electrolyte, but solid polymer. SMD aluminum electrolyte capacitors are the most common capacitors on graphics cards.

The two electrodes of the chip aluminum electrolytic capacitor are connected to the positive and negative poles of the power supply. After a while, even if the power is disconnected, there will still be a residual voltage between the two pins. We say that the chip aluminum electrolytic capacitor has stored charge. A voltage is established between the plates of the SMD aluminum electrolytic capacitor to accumulate electrical energy. This process is called the charging of the SMD aluminum electrolytic capacitor. The charged SMD aluminum electrolytic capacitor has a certain voltage at both ends. The process by which the stored charge of the chip aluminum electrolytic capacitor is released to the circuit is called the discharge of the chip aluminum electrolytic capacitor.
