Aluminum electrolytic capacitors are polarized capacitors that contain an anode of pure aluminum foil, a thin oxide layer on the aluminum and an electrolyte impregnated paper as its dielectric layer. They are called aluminum electrolytic capacitors because their construction and operation depends upon the principles of electrolysis. In other words, the electrolysis of an electrolyte solution is used to form an aluminum oxide on the surface of the anode.

The MAL203124681E3 series aluminum electrolytic capacitor is a kind of polarized capacitor with a large capacitance. It has a wide temperature range of -40℃~+85℃, a voltage range of 10V~400V, and a wide capacitance range of 1μF~10000μF. It is often used in DC filtering, high frequency resonance, signal coupling and bypass, charging and discharging circuit.

Compared to the traditional electrolytic capacitor, the MAL203124681E3 series has the advantages such as low ESR, fast charge and discharge, high dielectric strength, excellent heat dissipation, and more stability and reliability. These features make it suitable for a variety of applications where high performance, stability and reliability are a must.

In terms of its working principle, the capacitor is first charged by applying an electrical signal to the capacitor\'s terminals. As the electric current passes through the capacitor, a pile of electrons collects at the anode, and a corresponding negative charge builds up at the cathode. This arrangement of charge creates an electric field between the two leads that causes a separation of positive charge and negative charge at the terminals of the capacitor. This is the reason why the capacitors are called “electrically polarized” because the separation of charge makes it impossible for them to work correctly with alternating current.

As the name implies, an electrolytic capacitor works by electrolysis, wherein an electrolyte solution is used to displace electrons from the anode of the capacitor. The displaced electrons cause an oxide to form on the anode, which serves as the capacitor’s dielectric layer. This dielectric layer allows current to pass through it more easily, making it a higher-quality capacitor capable of storing more charge than traditional capacitors.

In conclusion, the MAL203124681E3 aluminum electrolytic capacitor is a polarized capacitor with a wide voltage range of 10V~400V, a wide capacitance range of 1μF~10000μF, and a wide temperature range of -40℃~+85℃. With its low ESR, fast charge and discharge capabilities, high dielectric strength, and excellent heat dissipation, it is ideal for DC filtering, high frequency resonance, signal coupling and bypass, charging and discharging circuit and other applications. Furthermore, it has an impressive capability of storing a large amount of charge due to its effective working principle.
