Aluminum electrolytic capacitors, also known as electrolytic capacitors, are mainly divided into two categories: electronic equipment type - aluminum shell electrolytic capacitor (ECA-2AMR47I in this case) and motor type - aluminum shell electrolytic capacitor. They are widely used in various electronic equipment, such as electronic calculators, automatic computer control instruments, audio-visual equipment, electronic inductor coils, power supplies, radios, televisions, etc. The working principle of aluminum electrolytic capacitors can be summed up as follows.

When a positive potential is applied to the anode of the aluminum electrolytic capacitor, a great amount of positive ions are attracted to the anode. The ions accumulate on the surface of the anode and form a thicker layer of aluminum oxide (Al2O3). The thicker the oxide layer, the lower the capacitance. The capacitance of the aluminum electrolytic capacitor is achieved when the thickness of the oxide layer is balanced with the applied potential.

The performance of the aluminum electrolytic capacitor is superior to other capacitors because its structure uses a dielectric that is insensitive to temperature and humidity. The dielectric of an electrolytic capacitor also allows for a much higher capacitance than other types of capacitors. This makes the aluminum electrolytic capacitor suitable for applications requiring high capacitance, such as large scale audio amplifiers, electronic controls, switching power supplies, and multiple stage amplifiers.

The aluminum electrolytic capacitor is also widely used in low frequency amplifier stages, voltage regulators, power filters, high frequency filters and power input lines. It is also used in Battery-backed DC power supplies, such as those found in computers and digital cameras. The capacitor is also extremely reliable and has a long service life.

In terms of application field, ECA-2AMR47I is an aluminum electrolytic capacitor with a capacitance of 47µF and rated voltage of 25Vdc. It is used in various consumer electronics products as well as various commercial products, such as battery table table radios, power input lines, filters. amplifier stages, voltage regulators, DC power supplies, etc.

To conclude, the aluminum electrolytic capacitor is a highly reliable component that is used in various applications requiring high capacitance and performance under harsh environmental conditions. The application field of ECA-2AMR47I and its working principle was summarized in this article.
