Introduction of electrolytic capacitors

1.1 Overview 😋Electrolytic capacitors should be called electrolytic capacitors because one of the electrical stages of such capacitors is not a metal but an electrolyte or metal oxide. In short, the conductive carriers of this electrode are no longer electrons but ions. This is the basic characteristic of electrolytic capacitors. Now. According to the characteristics of [...]

The principle of corrosion technology of aluminum foil of electrolytic capacitor

🔊In the production of aluminum electrolytic capacitors, increasing the capacitance value per unit volume is the direction of continuous improvement of capacitors. The capacitance is proportional to the effective area of the electrode surface, so the most effective way to expand the capacitance of aluminum electrolytic capacitors is to increase the effective surface area of the [...]

High frequency and low resistance the role in switching power supply

High-frequency low-impedance refers to the ability of the capacitor to withstand ripple current and its small internal resistance. Compared with ordinary, the product itself is not easy to heat in the circuit and cause premature failure. In particular, because of its miniaturization, light weight and high efficiency, switching power supply modules require small and large electrolytic [...]

The electrolytic capacitor and film capacitor principle

Film Capacitor principle  The film is processed to allow metal atoms to attach to the film. The metal is evaporated under vacuum (1200 ° C for aluminum) to the surface of the treated film (the film is cooled to -25 ° C to -35 ° C) to form a metal layer. If the dielectric is short-circuited, [...]
