Aluminum electrolytic capacitors are widely used in electronic and electrical equipment due to their advantages of large capacity, low the equivalent serial resistance, and long life. The EET-UQ2S681LA is a type of aluminum electrolytic capacitor with a diameter of 10x25mm. It has a rated voltage of 5 V, a capacitance of 680 uF, and a rated operating temperature of -40 to +105 degrees Celsius.

The EET-UQ2S681LA is mainly used for smoothing, filtering, and current input in power electronic circuits. It can also be used for peak current, reduce the power supply ripple, and prevent power instantaneous peak caused by switch on and off. As an aluminum electrolytic capacitor, its capacity is far greater than other capacitors, which makes it more suitable for treating relatively large input signals.

The working principle of the EET-UQ2S681LA primarily involves the transfer of energy from one conductive plate to another by means of an electrolytic solution. It consists of an aluminum foil covered by an electrolytic film, a separator made of paper, and a conductive layer called the cathode. The process begins when the positive terminal of the capacitor is connected to the positive supply. Then, an electric current is generated, which flows through an electrolytic solution between the two foils. This process causes one foil to become positive and the other to become negative. Capacitance is created as the electric current passes through the electrolytic solution and between the two plates, and voltage corresponding to the capacitance is stored in the capacitor. When the capacitor is discharged, the voltage is lost, and the electrolytic solution returns to neutral.

In summary, the EET-UQ2S681LA is an aluminum electrolytic capacitor that is used in a variety of applications. It is specifically designed with a rated voltage of 5 V, a capacitance of 680 uF, and a rated operating temperature of -40 to +105 degrees Celsius. Its primary purpose is to reduce ripple and peak current, as well as avoiding instantaneous peak power caused by the switching of devices on and off. The working principle involves the generation of an electric current through the electrolytic solution, which creates capacitance between the two plates of the capacitor and stores voltage corresponding to the capacitance.
