Working Principle

Aluminum electrolytic capacitors are composed of an anode foil, cathode foil, electrolyte, and an insulator paper contained in its case. The metal foil act as electrodes, and the insulator paper acts as a separator between the two foils. The electrolyte is an ionic conductor and acts as the capacitance of the capacitor.When a voltage is applied to the anode and cathode, the anode foil attracts the positive ions from in the electrolyte and become anodic aluminum oxide film, while the cathode foil releases negative ions to the electrolyte. This creates a capacitance between the two foils.

The 63YK2200M18X35.5 capacitors have high capacitance, high thermal stability, and low leakage current. The capacitance is determined by its thickness and surface area of the anodic aluminum oxide film. This type of capacitor has an anode made of pure aluminum and an alkaline electrolyte, which results in an excellent self-healing property.

Conclusion

The 63YK2200M18x35.5 aluminum electrolytic capacitor is a high-performance capacitor used for a variety of applications. It has high capacitance, low leakage current, and excellent high frequency performance due to its low ESR and ESL values. This type of capacitor is suitable for output bypass coupling, flash memory decoupling, active LC filter circuits, and other high-power and high-frequency circuits.
