CGS312U100R2C

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as "super capacitors", are a type of capacitor that is commonly used in many electronic components, including the CGS312U100R2C. Due to their unique structure, they offer superior performance compared to other types of capacitors.

The main components of aluminum electrolytic capacitors are two aluminum foil plates, two electrolytic papers and the electrolyte, which is usually made of ethylene glycol and water. The two aluminum foil plates are electrochemically etched, creating a large number of microscopic pores on their surface. These microscopic pores can increase the capacitance of the capacitor. The two aluminum foil plates are then filled with electrolyte, and the electrolyte is sealed inside the capacitor with the electrolytic paper.

The working principle of the CGS312U100R2C is based on Faraday\'s law of electrolysis, which states that the amount of electric charge that passes through the capacitor is proportional to the voltage applied. The voltage is applied between two points on the capacitor, the anode and the cathode. When a voltage is applied across the capacitor, the anode and cathode become polarized and electrons flow from the anode to the cathode, creating a capacitance. As the applied voltage increases, more electrons pass through the capacitor, thus increasing the capacitance.

Aluminum electrolytic capacitors are available in a variety of sizes and ratings. The main characteristics of the CGS312U100R2C are its capacitance, voltage rating, and temperature range. It has a maximum capacitance of 100 μF, a voltage rating of 63V, and can operate in temperatures from -40°C to +85°C. Aluminum electrolytic capacitors are ideal for use in applications where high levels of voltage and current must be handled, such as power-supply circuitry, or where high temperature or moisture levels might be present.
