Aluminum electrolytic capacitors are widely used in many applications due to their high level of electrical performance and long-term reliability. The LGW2E821MELA50 is a surface mount type aluminum electrolytic capacitor with a maximum working voltage of 10Vdc and a rated capacitance of 2200uF. This capacitor is well suited for use in higher voltage, low current applications such as audio equipment, consumer electronics, and industrial control systems.

The LGW2E821MELA50 has a working temperature range of -25°C to +105°C and a maximum ripple current value of 5.0A. It is designed with an extended negative temperature coefficient (NTC) which ensures reliable operation under non-linear conditions. The robust construction features a long-life cathode electrolyte that increases the capacitance over time and reduces the leakage current. The capacitor also has stable electrical parameters over a wide range of temperature and frequency conditions.

The working principle of an aluminum electrolytic capacitor is based on the storage of electrostatic energy utilizing two metallic electrodes separated by an electrolyte. The two electrodes are typically made of aluminum and are connected to the external terminals of the capacitor. The electrolyte is composed of an aqueous solution of a metal salt and acts as the dielectric. The electrical parameters of the capacitor are controlled by the amount of electrolyte, the thickness of the aluminum foil electrodes and the temperature of operation.

The aluminum electrolyte capacitor is widely used in electronic devices such as AC adaptors, timers, power supplies, and digital circuits. In AC adaptors, the LGW2E821MELA50 functions as a smoothing capacitor and helps to reduce the peak voltage and ripple voltage of the AC current. In digital circuits, the capacitor helps to ensure a more stable voltage and reduce the amount of electromagnetic interference (EMI). In power supplies, the capacitor stores energy that is released during periods of peak demand.

The LGW2E821MELA50 is a valuable component for many different applications due to its high level of electrical performance, long-term reliability and wide temperature range. With its extended NTC and robust construction, it is well suited for use in higher voltage, low current applications such as audio equipment, consumer electronics, and industrial control systems.
