The product series contains products of different working voltages and different capacitances. It is mainly used in switching power supplies, ballasts, LED lighting, electric wire equipment, adapters, air conditioners, home appliances and other applications related to capacitor filters.

Working Principle

The working principle of the EKMH350VNN183MA40T aluminum electrolytic capacitor is based on the principle of electrolytic capacitors. Its core is composed of an insulating film, a conductive film, and an electrolyte. The two films are evenly coated with a conducting agent, which is composed of metal foil and aluminum foil. The two poles of the metal foil and aluminum foil form a capacitor as a whole. The electrolyte functions as an electrolyte and dielectric to link the two poles.

In operation, the metal foil serves as the anode and the aluminum foil serves as the cathode. When a predetermined voltage is applied to the two terminals, an electric field is generated across the insulating film, the individual ions of the electrolyte generate a large amount of current, thereby forming an electrolytic reaction. The positive and negative electrodes are formed in the aluminum foil. When the capacitor is started, the aluminum surface of the negative electrode is anodized to form a dielectric oxide film. With the continuous supply of direct current, the oxide film gradually thickens, increasing the dielectric constant of the entire capacitor. At this time, the current passing between the two electrodes simultaneously forms an electrolytic reaction to produce a stable capacitance.

Conclusion

EKMH350VNN183MA40T aluminum electrolytic capacitor is a cylindrical organic electrolytic capacitor, which is characterized by its high capacity, high voltage, shock absorption, good ripple current and excellent frequency characteristics. Therefore, it is widely used in various applications related to capacitor filters, such as switching power supplies, ballasts, LED lighting, electric wire equipment, adapters, air conditioners and home appliances. The working principle of this type of capacitor is based on the principle of electrolytic capacitors, and the positive and negative electrodes are formed in the aluminum foil.
