It is widely used in a variety of power supplies and circuits, especially in applications where a large capacitance is needed with a long life span and intense performance.

These capacitors are mostly used in modern electronics such as computer power supplies, TVs, radios, mobile phones and other electronic devices. They are also used in machine tools, industrial automatic production lines, automatic lifting platforms, medical equipment and other electronic devices.

Working Principle

ALF20C273EF040 aluminum electrolytic capacitors are made of aluminum foil and electrolyte molecules with a high capacitance and high volumetric efficiency. The electrolyte is usually a paste with dielectric properties.

An electric potential is applied to the electrodes of the capacitor, causing a separation of charges between the two electrodes. The electrolyte acts as a conductor and a dielectric. This causes the electrolyte to collect charges from the active electrode and deposit them on the non-active electrode. The difference in charge between the two electrodes causes a capacitance to be formed.

The capacitor stores electric energy because it takes time for electrons to travel through the electrolyte and reach the other electrode. The longer it takes, the higher the capacitance. Because of this, aluminum electrolytic capacitors are able to store large amounts of energy in a small package.

Conclusion

ALF20C273EF040 aluminum electrolytic capacitors are highly effective components for use in a variety of electronic circuit applications. They offer high levels of capacitance and performance, while allowing manufacturers to reduce the size and weight of their products. They are reliable and affordable, making them an ideal choice for many projects.
