Aluminum electrolytic capacitors are a type of capacitor that make use of an electrolyte to achieve a higher capacitance per unit volume. These capacitors are mainly used for filtering, decoupling, and smoothing in electrical and electronic circuits. The ECA-2EM470B is a surface mount type aluminum electrolytic capacitor with a high capacitance range of up to 470µF. It is made of a highly reliable conductive polymer tantalum solid electrolyte, which has high reliability, obtaining both duration life and stability. This capacitor is suitable for a wide range of applications, from high voltage to low voltage.

Working Principle

The working principle of aluminum electrolytic capacitors is based on Faraday’s law of electrolysis. This states that when a voltage is applied to the two electrodes of an electrolytic cell, the electrolyte will be formed on one of the electrodes and an equivalent amount of ions will be released to the other electrode. This forms the basis of the electrolytic capacitor. The electrodes are made of aluminum foil that is coated with a thin layer of electrolyte. The electrolyte acts as an insulator between the two electrodes and prevents electrical current from flowing across them. When a voltage is applied to the capacitor, it causes the electrolyte to form on the aluminum foil and cause the capacitance of the capacitor to increase.
