Aluminum Electrolytic Capacitors

LAO-50V472MS37PX#B Application Field and Working Principle

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are one of the most commonly used polar capacitors. It is widely used in power equipment, welding machines, communication base stations, battery packs, computers, televisions, etc. It is known as a “universal capacitor” in the electronics sector. The LAO-50V472MS37PX#B-type aluminum electrolytic capacitor is a product of the Aptiv brand, used to filter and bypass noisy signals, protect other circuits and control output current. It is a Non-polar capacitor with small size, low ESR, small current leakage, high working voltage, high capacitor density and high temperature.The LAO-50V472MS37PX#B aluminum electrolytic capacitor consists of three parts: an anode aluminum foil, a dielectric oxide film and a cathode foil/electrolyte. The aluminum foil is an anodized foil on which an oxide film is formed by electrochemical oxidation. The oxide film is an insulator. The cathode is either an aluminum foil or an electrolyte. The anode aluminum foil is formed with a positive pole, and the cathode is divided into two kinds: one is aluminum foil, the other is vitrified electrolyte. The main function of the aluminum foil is to increase the capacitance and reduce the ESR. The electrolyte is mainly used to reduce the equivalent series resistance (ESR) and increase the working temperature of the capacitor. The pressure-sensitive adhesive paper/film is a protective film used as an insulating layer for the upper and lower electrodes of the capacitor.The working principle of the LAO-50V472MS37PX#B aluminum electrolytic capacitor is based on the principle of capacitor. That is, when the two electrodes of the capacitor are connected to the power supply, a certain potential difference is generated between the two electrodes, and an electric field is generated in the dielectric, so that a potential difference is formed between the two plates. The electric charge on one plate is compensated by the electric discharge on the other plate, so that the capacitor is basically static.When the capacitor is in active mode, the electric energy stored between the two electrodes can be converted into a certain magnitude of alternate current, which can be used to drive other circuits, reduce the current ripple, filter and stabilize the DC voltage, or test certain signal changes.Based on the above, the application field and working principle of the LAO-50V472MS37PX#B aluminum electrolytic capacitor is clear: it is mainly used to filter and bypass the signal, attenuation signal changes, and protect other circuits or control the output current. Its working principle is based on the principle of capacitor and stores electric energy between two electrodes to achieve a certain magnitude of alternate current output.
