Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors exist in most modern electronic devices, including televisions, computers, mobile phones, and audio equipment. They are used to store electrical energy, smooth out DC currents, and are vital to the function of most digital circuits. The ELXV630ELL121MJ20S aluminum electrolytic capacitor is a widely used product, designed for applications such as filtering, energy storage, and signal coupling. It is particularly well suited for high frequency and high ripple current applications due to its low equivalent series resistance (ESR) and low leakage current.

ELXV630ELL121MJ20S

ELXV630ELL121MJ20S is an aluminum electrolytic capacitor with an 85°C rated temperature. It features a capacitance range of 680-800µF, a voltage rating of 63VDC, and a lead pitch of 5x6.5mm. Its low ESR and low leakage current allow it to be used in high ripple current and high frequency applications, while its screw-terminal mounting offer excellent physical and electrical stability. This capacitor is suitable for use in SMPS, UPS, solar inverters, and other DC/DC converter circuits. It is also ideal for AC/DC power supplies, inverter and motor drivers, audio amplifiers, and other equipment that require low ESR in the circuit.

Working Principle of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are composed of two electrodes separated by a solid dielectric material, an electrolyte, and a separator. The two electrodes are made from aluminum foil using chemical and physical deposition processes. The aluminum foil electrodes are then coated with a layer of an oxide coating, followed by the application of electrolyte. The separator is then added to keep the two electrodes apart. The working principle of an aluminum electrolytic capacitor is similar to that of a regular electrolytic capacitor. The dielectric layer acts as the insulating material between the two electrodes, allowing the capacitor to store electrical energy.

When an electrical current hits the capacitor, the positive and negative charge of the currents causes the oxide layer on the aluminum electrodes to become polarized. This creates a physical separation between the two electrodes, allowing the capacitor to store electrical energy. As the capacitor discharges, these opposite charges come together again, allowing the capacitor to ‘store’ electrical energy again. This process can repeat many times and is responsible for the functioning of aluminum electrolytic capacitors.
