The importance of capacitors

Aluminum electrolytic capacitors play an important role in modern industry. Aluminum electrolytic capacitors are polar electrolytic capacitors. The anode electrode (+) is made of aluminum foil with an etched surface. The aluminum foil is anodized and covered with a thin aluminum oxide insulating layer. dielectric. The aluminum oxide is coated with electrolyte, which is the cathode (-) of the capacitor. There is an additional layer of aluminum foil, called "cathode aluminum foil". The cathode foil will be in contact with the electrolyte, connecting to the negative terminal of the capacitor. Aluminum electrolytic capacitors can be divided into liquid aluminum electrolytic capacitors and solid aluminum capacitors according to the type of electrolyte. Products have been widely used in consumer electronic products, communication products, computers and peripheral products, instrumentation, automation control, automotive industry, optoelectronic products, high-speed railway and aviation and military equipment.
