2. Working principle

The MAL213660222E3 aluminum electrolytic capacitor is a kind of polarized capacitor. It mainly consists of aluminum plates, non-polar electrodes and electrolytes, which are connected in series in the internal structure. The aluminum plates are first anodized and the internal dielectric oxide film is formed, and the non-polar electrodes are connected on both sides respectively. The electrolyte is filled between the two plates, and the ions in the electrolyte form a weak dynamic electric field between the aluminum plates, producing a positive and negative potential difference. Under the effect of an external DC voltage, current will flow through the capacitor and cause electricity in the capacitor.

The voltage of MAL213660222E3 aluminum electrolytic capacitors is mainly determined by the anode oxidation layer. The greater the voltage, the thicker the anode oxidation layer. The capacitance is mainly determined by the area of aluminum foil and the thickness of dielectric oxide film. The thinner the oxide layer, the larger the capacitance. The stability of the capacitor is mainly determined by the quality of the electrolyte. The higher the purity of the potassium hydroxide used, the better the insulation effect and the greater the reliability of the capacitor.

In conclusion, MAL213660222E3 aluminum electrolytic capacitors can be used in audio power amplifiers, switching power supplies, DC to DC converters, rectifying circuits and low ripple filters. Its working principle is mainly related to the strength and purity of the oxygen passivation layer, the area of the aluminum foil and the quality of the electrolyte.
