Aluminum electrolytic capacitors are widely used in the electronics industry. ECO-S2DA821EA is a kind of aluminum electrolytic capacitor. It has a large capacity, wide operating temperature range, good thermal stability and small size. Its usage and working principle are as follows:

Application Field

The ECO-S2DA821EA aluminum electrolytic capacitor is suitable for desktop computers, notebook computers, mobile phones, car audio systems and other electronic products used in fields with strong interference. It can reduce noise, filter power supply, and provide stable voltage and current for circuit operation, which can improve the life of electronic devices. Moreover, it can also be used in storage fields, such as digital cameras or other portable electronic devices.

Working Principle

Aluminum electrolytic capacitors mainly use the fact that electrolyte has a higher dielectric constant than other liquids. The electrostatic capacity of a capacitor depends on the surface of the electrode, the thickness of the insulating material and the volume of the electrolyte. To use this electrostatic capacity, electrodes are made from aluminum foils. Aluminum foils have a thin oxide layer on the surface, which acts as an insulator. Electrolyte is added between the two electrodes and a voltage is applied to the electrodes. The oxide layer of the aluminum foil forms the insulating film. The formed electric field is increased by the electric field of the oxide layer, thus increasing the capacity.

The ECO-S2DA821EA aluminum electrolytic capacitor is a radial-lead aluminum electrolytic capacitor, mainly composed of aluminum foil, electrolyte and insulation film. When the voltage is applied, a photocatalytic reaction occurs between the aluminum foil and the electrolyte. This will form a high dielectric insulation oxide film with a substantial capacitance on the aluminum foil. It acts as a filter, which filters out a large amount of noise of power and provides stabilized voltage to the circuit.

Conclusion

In conclusion, the ECO-S2DA821EA aluminum electrolytic capacitor has a wide range of application fields and stable power supply performance. It can be widely used in desktop computers, notebook computers, mobile phones, car audio systems and other electronic products used in fields with strong interference, increasing the life of electronic devices. The working principle of the capacitor is mainly based on the fact that electrolyte has a higher dielectric constant than other liquids.
