The role of electrolytic capacitors?
Visit：3535 Date：2019-03-07
Electrolytic capacitors are usually made of metal foil (aluminum/bismuth) as a positive electrode, an insulating oxide layer of aluminum foil (aluminum oxide/ruthenium pentoxide) as a dielectric, and electrolytic capacitors are divided into aluminum electrolytic capacitors and tantalum electrolysis by their positive electrodes. Capacitor. The negative electrode of the aluminum electrolytic capacitor is composed of a thin paper/film or an electrolyte polymer immersed in an electrolyte liquid (liquid electrolyte); the negative electrode of the tantalum electrolytic capacitor is usually manganese dioxide. Since the electrolyte is used as the negative electrode (note that it is distinguished from the dielectric), the electrolytic capacitor is named after it.
