Aluminum Electrolytic Capacitors

381LX681M315A452 Application Field and Working Principle

Aluminum electrolytic capacitors are an important component of passive components, and its main use is to store electrical energy. It is mainly composed of an aluminum oxide film formed on the inner surface of the aluminum foil and a absorbent saturated with electrolyte. The 381LX681M315A452 aluminum electrolytic capacitor is a special capacitor with the characteristics of high electrostatic capacity, high insulation, and small size.The 381LX681M315A452 aluminum electrolytic capacitor can be used in various applications, such as audio-visual equipment, communications equipment, electronic equipment, computers, instrumentation, audiovisual players, and so on. It is especially suitable for circuit design and distribution of charging and discharging power supply, allowing users to quickly charge and discharge the circuit, and maintain power supply balance.The working principle of the 381LX681M315A452 aluminum electrolytic capacitor is also very simple. Two aluminum foils are used as electrodes and are evenly separated by a very thin insulating oxide film. Between the electrodes, an absorbent saturated with electrolyte is filled, forming an electrolyte capacitor. This capacitor has a thin insulating layer between the two electrodes, a thicker positive electrode in the middle, and a thinner negative electrode on the outside.When the capacitor is connected to the power supply, a certain electric field will be generated in the interlayer, which causes the positive electrode and the negative electrode to charge and discharge. The positive electrode connected to the power supply accumulates electrons and forms a positive charge. The negative electrode loses its electrons to create a negative charge. Hence, an electric field is generated between the positive and negative electrode, and electric charges accumulate and discharge alternately, forming a capacitor.The 381LX681M315A452 aluminum electrolytic capacitor has a high loss angle, which makes it especially suitable for applications with high humidity and temperature. Its high power supply balance and reliable storage of electrical energy make it an ideal choice for circuit design and distribution of power supplies. This capacitor has a wide range of uses, from audio-visual equipment, communications equipment to electronic equipment and computers. It is especially useful for power supplies in instrumentation, audiovisual players, and other electronic devices.
