Aluminum Electrolytic Capacitors are widely used for energy storage and filtering applications in various electronic circuits. The LGU2A821MELZ is a high-reliability, low-leakage, aluminum electrolytic capacitor particularly suitable for use in critical applications where both high capacitance and long life are required.

The LGU2A821MELZ has a capacitance of 2.2 µF, a rated voltage of 10V, a rated ripple current of 350mA, and a temperature range of -40 to +85°C. It is particularly suitable for storage applications such as energy planning, load balancing, and power protection, as well as for filtering applications such as signal pre-filtering, harmonic suppression, and transient voltage suppression.

This aluminum electrolytic capacitor works by converting an electrical signal into a redistribution of electric charge. When a positive voltage is applied to the positive electrode of the capacitor, electric current is passed through the capacitor’s electrodes and electrolyte, forming a film of metal oxide at the negative electrode. This film acts as a dielectric and stores the initial electric charge.

When a voltage of the opposite polarity is applied, the charge stored in the capacitor is discharged back into the circuit. The amount of electric charge stored in the capacitor and the rate of discharge are determined by the capacitors electric characteristics, such as capacitance, voltage rating, and ripple current.

The LGU2A821MELZ is a reliable, cost-effective aluminum electrolytic capacitor that is suitable for energy storage and filtering applications in a variety of electronic circuits. Its low leakage and high capacitance make it an ideal choice for use in critical applications where long life and high performance are required.
