Aluminum electrolytic capacitors are capacitors that function using an electrolyte, typically an ionic conductive gel or liquid for static electricity to provide electric energy. They are made up of two aluminum foils with a paper spacer that is impregnated with electrolyte, and an anode made of aluminum oxide. The aluminum oxide film acts as the dielectric and the aluminum foils act as the plates. They are commonly used in communication, industrial and transportation applications.The ECA-2EM4R7 capacitor is an aluminum electrolytic capacitor that is designed for both low leakage and long life. It has a rated voltage of 2.5V, a capacitance of 470μF and a capacitance tolerance of ±20%. This capacitor is ideal for applications such as motor control, switching power supplies, DC/DC converters, and amplifier circuits that require low leakage and long life.The working principle of an aluminum electrolytic capacitor is based on the behavior of an electrolyte when it comes into contact with a certain electrical charge. The electrolyte forms an isotropic film on the metallic surface of the capacitor, which acts as a dielectric material. This film helps to store electric charge on the capacitor, which is then transferred through the electrolyte and into the external circuit. When the capacitor is connected to a direct current source, a potential difference is created between its terminals. This causes a build up of electric charge on the capacitor\'s plates, which creates an electric field between them. The electric field produces an opposing force, providing the capacitor with its capacitance.The ECA-2EM4R7 capacitor is designed to operate with very low leakage current, making it highly reliable and ideal for applications such as motor control, switching power supplies, DC/DC converters, and amplifier circuits. Its long life expectancy of up to 2000 hours at rated temperature and voltage makes it a popular choice for applications that require a long lifespan. Its low-impedance design also helps to reduce ESR (equivalent series resistance) and mitigate voltage spikes that can occur in applications with high capacitive loads.In conclusion, the ECA-2EM4R7 aluminum electrolytic capacitor is a reliable and long lasting solution for applications that require high capacitance, low leakage and long life. Its low-impedance design, combined with its capacity to store electric charge, makes it an ideal choice for a wide range of applications in communication, industrial and transportation applications.
