ECO-S2HP680CA Application Field and Working Principle of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various electronic devices. ECO-S2HP680CA is a kind of aluminum electrolytic capacitor with excellent electrical performance and strong anti-interference ability. This paper introduces its application field and working principle in detail.

1. Application Field of ECO-S2HP680CA

ECO-S2HP680CA is mainly used in high-frequency circuits and is suitable for high pulse load current application scenarios, such as TVs, computers and telecom devices. Because of its low leakage current and low ESR value, it can effectively reduce the main circuit and reduce the system EMI (electromagnetic interference). The ripple current is up to 1,200mA, so it has excellent electrical performance. It can also play a role in reducing the harmonic noise in the circuit and improving the signal-to-noise ratio.

2. Working Principle of Aluminum Electrolytic Capacitors

The working principle of aluminum electrolytic capacitors is based on the principle of polarization. It consists of an aluminum foil, an insulating film, an electrolyte, and a sealing shell. The anode of the capacitor is an oxidized aluminum foil with many negatively charged oxide molecules. The cathode is graphite or other conductive materials. When the external voltage is applied, the negative charges in the oxide molecules on the anode plate move to the lower potential, forming a positive electrode. The cations of the electrolyte liquid fill the film and form the electric field. The ions of the electrolyte liquid constitute a dielectric film layer, thus forming an electric double layer capacitor.When the current passes through the capacitance, the external voltage will make the anode and the cathode plate produce a polarized layer, which allows the current to flow and stores energy. When the current stops, the positive and negative charges in the oxide molecules continue to attract each other and move away from the anode plate. This charging process allows the current to flow back from the anode and the capacitor to obtain electrostatic energy.Aluminum electrolytic capacitors have the characteristics of large capacity, low equivalent series resistance, low leakage current and excellent electrical performance, making them widely used in various electronic devices.

3. Conclusion

ECO-S2HP680CA is a type of aluminum electrolytic capacitor with excellent electrical performance and strong anti-interference ability. It is mainly used in high-frequency circuits and is suitable for high pulse load current application scenarios. Its working principle is based on the principle of polarization, which allows the anode and the cathode plate to generate a polarized layer and store energy by charging and discharging processes.
