LGU2C471MELZ

Aluminum electrolytic capacitors are one type of passive electronic components with a wide range of applications. They are based on the principle of electrolytic polarization, which uses the anode electrolyte reaction electrochemical effect to generate an additional electric field to increase the capacitance. The LGU2C471MELZ is an aluminum electrolytic capacitor with a long life, temperature and high reliability.

Working Principle

The LGU2C471MELZ is a type of aluminum electrolytic capacitor, which relies on a polarized electrolyte that covers two layers of aluminum foil. A separator is placed between the aluminum layers, and the two layers of aluminum are connected to a positive plate and a negative plate respectively. When a voltage is applied, the positive plate polarizes the electrolyte, allowing positive ions to pass through and providing additional electric field which increases the capacity of the capacitor. This is known as the electrolytic polarization effect. The electrochemical reaction between the aluminum foils and the electrolyte generates an electrical energy, which is stored in the capacitor.

Significant Application Fields

Aluminum electrolytic capacitors, including the LGU2C471MELZ, are used in various application fields, such as power supplies, filters, decoupling and so on. Some of the most common applications are listed below.

• Power Supply: Aluminum electrolytic capacitors are often used in the power supply system of electronic equipment to store energy and filter ripple caused by rectification.
• Filtering: Aluminum electrolytic capacitors can remove AC components from the waveforms and keep the signal waveform clean, thus improving the signal-to-noise ratio.
• Decoupling: Aluminum electrolytic capacitors are often used in circuits as bypass capacitors to provide a low impedance path to ground, reducing unwanted signal oscillations.
• Power Line Filtering: Aluminum electrolytic capacitors can reduce the interference and noise on the power line and improve the signal-to-noise ratio.
• Output Filter: Aluminum electrolytic capacitors can be used as a low frequency filter to reduce DC component and ripple voltage in the output load.
