Aluminum electrolytic capacitors are one of the most popular and widely used capacitors on the market today. They are used in a wide variety of electronic circuits and applications, from the small electronic components in consumer electronics to the large components in industrial control systems. The LGN2E391MELY40 is a type of aluminum electrolytic capacitor that is used for high reliability applications.
The LGN2E391MELY40 is a polarized aluminum electrolytic capacitor that has a low equivalent series resistance (ESR) of 0.12 ohms, and is rated up to 100V DC. It is a long life capacitor with a design life of 1000 to 2000 hours at 85°C and has a rated capacitance of 390uF. The LGN2E391MELY40 is specifically designed for use in high reliability applications, such as medical and military equipment, where extreme temperatures and surges of large current must be considered during design.
The capacitance of an aluminum electrolytic capacitor is determined by the area of the aluminum foil and the gap between the aluminum foils. This gap is filled with an electrolyte such as boric acid or sulfuric acid, the type of electrolyte used affecting the voltage and temperature ratings of the capacitor. The aluminum foil is then rolled and placed in a metal or plastic container, which acts as the capacitor’s case.
The working principle of an aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. When an electrical voltage is applied across the capacitor, an electric current flows through the electrolyte and deposits aluminum oxide on the cathode, which serves as an insulating layer. This layer effectively increases the capacitance of the capacitor. As the electric current flows, the oxide layer grows thicker, which increases the capacitance of the capacitor until it reaches its maximum capacitance value.
The LGN2E391MELY40 is a popular choice for applications such as power converters, motor control, and other industrial applications due to its high reliability and capability of withstanding large surges of current. It is also used in consumer electronics such as broadcasting equipment and medical imaging scanners. The capacitor can also be used in lighting applications such as street lights and traffic lights, as it is able to withstand large pulses of light.
In summary, the LGN2E391MELY40 is an aluminum electrolytic capacitor that is designed for high reliability applications. It has a low equivalent series resistance (ESR) of 0.12 ohms and is rated up to 100V DC. The capacitance of the capacitor is determined by the area of the aluminum foil and the gap between the aluminum foils, where an electrolyte such as boric acid or sulfuric acid is used to increase the voltage and temperature ratings of the capacitor. The working principle of the capacitor is based on Faraday’s law of electrolysis. It is most commonly used in power converters, motor control, and other industrial applications, as well as consumer electronics such as broadcasting equipment and medical imaging scanners.
