Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are a common type of capacitor, and the materials of the electrodes are metallic parts and electrolytic capacitor plate respectively. The working principle of aluminum electrolytic capacitor is based on the reverse commutation of anode and cathode in electrolyte. The reverse commutation presents a charging state and a spending state. The huge capacity of aluminum electrolytic capacitor is related to the electric action that occurs at the reverse commutation. Part of the electric energy will be stored in the capacitor and be released in an opposite direction.

397LMX450M2EG, as a type of aluminum electrolytic capacitors, is widely used in a variety of applications and electronics industry. The capacitors have all kinds of features such as wide operating temperature range, small volume, long life expectancy and reliable performance. In the computer industry, aluminum electrolytic capacitors are used for power control and to reduce EMI (electromagnetic interference). In the telecommunications industry, aluminum electrolytic capacitors are often used for similar applications such as audio filtering, power distribution, signal conditioning, and buffer power supplies.

Specifically, the electrolyte-filled aluminum electrolytic capacitors consist of a positively charged metal core rod (anode) and a sheet of electrolyte-impregnated paper or sintered aluminum as the negative electrode (cathode). The anode is then sealed in a robust aluminum enclosure which acts as the dielectric. The dielectric between the anode and the cathode is the electrolyte which separates the two electrodes. When an electrical signal is applied across the electrodes, the electrolyte acts as a semiconductor and the anode and cathode both travel in reverse directions. This action creates an electrical charge between the electrodes and the capacitor holds the charge until the electrical signal is removed.

Also, the electrolyte is chemically charged with an acid or alkaline solution and will decompose when the electrolyte reaches a certain voltage level, due to chemical reaction or heat dissipation, the electrolyte will start to break down, allowing current to flow through the aluminum electrolytic capacitor. This is why it\'s important to choose an appropriate voltage rating when selecting an aluminum electrolytic capacitor, as the capacitor will only last its life expectancy when the voltage applied to the capacitor does not exceed the capacitors rated voltage.

Thus, the working principle of aluminum electrolytic capacitor is based on the commutation of anode and cathode in an electrolyte, which allows the capacitor to store energy. The dielectric between the anode and the cathode is the electrolyte which separates the two electrodes. When there is an electrical signal, an electrical charge is generated between the electrodes, and the capacitor will hold the charge until the electrical signal is removed. Due to the reliable performance, long life and the wide operating temperature range, the aluminum electrolytic capacitors like the 397LMX450M2EG are widely used in electronics industry, computer industry and telecom industry.
