HES501G400V2C

Aluminum electrolytic capacitors, also known as electrolytic capacitors, aluminum electrolytic capacitors, or electrolytic capacitors, are capacitors in which one terminal is insulated from the external environment by a thin oxide layer. HES501G400V2C is a widely used model of aluminum electrolytic capacitors.

Application Field

HES501G400V2C aluminum electrolytic capacitor has many application areas, such as electronic kits, professional equipments(radar, satellite communication systems, medical equipments, etc.). It is mainly used to store and transfer energy in the power frequency and low frequency filtering areas to improve the power supply level. It can also be used in areas requiring a large capacity, such as in measuring instruments, automatic control constants. It is also vastly applied in the industrial area, such as locomotives, vehicles, complex products, industrial operation parts, electronic inverter, anti-lock braking system, stabilization unit, etc.

Working Principle

HES501G400V2C aluminum electrolytic capacitor is a type of passive components. It is made of electrolyte and two pieces of thin aluminum foil. The dielectric of the capacitor is the electrolyte formed by the anode foil and the electrolyte. Applied with the reverse voltage, aluminum anodic oxide film is formed as the insulation layer. This forms the basic working principle of the HES501G400V2C aluminum electrolytic capacitor. The electrodes of the capacitor are made from pure aluminum, which is then rolled into a thin sheet. The sheets then become the anode and cathode. The electrolyte is then sprayed between the two sheets, forming the dielectric. The anode is then etched, forming a porous surface and increasing the surface area of the electrode.

When applying a reverse voltage to the capacitor, an electric field is created. As the field strength increases, the aluminum anodic oxide film increases in thickness. This further increases the insulation property of the capacitor. The thickness of the dielectric is approximately 0.1 μm, which is 100 times larger than the thickness of the normal dielectric. This helps further protect the capacitor from any harm. The oxide film formed by electric field is also beneficial for interference, electromagnetic compatibility, as the dielectric absorbs the macroscopic noise.

Conclusion

HES501G400V2C aluminum electrolytic capacitor is widely used in a variety of applications. It is mainly used to store and transfer energy in the power frequency and low frequency filtering area to improve the power supply. Its working principle is based on its electrolyte, anode foil, and cathode foil. When applying a reverse voltage, an electric field is created resulting in the formation of the aluminum anodic oxide film. This film further increases the insulation property of the capacitor. All in all, HES501G400V2C aluminum electrolytic capacitor has many applications, making it one of the most versatile capacitors used today.
