Introduction of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most common types of capacitors used in both AC and DC circuits. They have a wide range of applications and offer many benefits such as long life, high capacitance and high ripple current handling capabilities.

Working Principle of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors work on a similar principle as other types of capacitors, but they are constructed differently with an electrolyte solution replacing the dielectric material found in standard capacitors. A thin layer of aluminum oxide is formed on the surface of the aluminum cathode foil when passing an electric current through it. This layer acts as an insulator and prevents current from passing through. The anode foil (aluminum) is then sandwiched between this Aluminum oxide layer and the electrolytic solution. The combination of the thin layer of aluminum oxide, the electrolyte, and the aluminum create a capacitor.The capacitance of the capacitor is determined by the area of the foil and the thickness of the oxide layer which is often referred to as its “dielectric strength”.

ERHB5H1LGC272MF85U application fields and working principle

ERHB5H1LGC272MF85U is an aluminum electrolytic capacitor produced by Elko, and it features long life and high surge current handling ability. This capacitor is mainly used in decoupling, filtering, and bypass circuit applications such as in switching power supplies or automotive DC systems. The working principle of ERHB5H1LGC272MF85U is the same as other aluminum electrolytic capacitors. It is constructed with an electrolyte solution between the anode and the aluminum cathode foil. An electric current is passed through the aluminum foil, which forms a thin layer of aluminum oxide on the surface. This thin layer of aluminum oxide acts as an insulator and prevents current from passing through, thus increasing the capacitance of the capacitor.

Conclusion

Aluminum electrolytic capacitors are a widely used type of capacitors that offer a variety of advantages in terms of longevity, high capacitance, and high surge current handling abilities. ERHB5H1LGC272MF85U is an aluminum electrolytic capacitor produced by Elko, and it is mainly used in decoupling, filtering, or bypass circuit applications. Its working principle is the same as other aluminum electrolytic capacitors – an electric current is passed through the aluminum foil, which forms an insulating thin layer of aluminum oxide between the anode and the aluminum cathode foil. This thin layer of aluminum oxide increases the capacitance of the capacitor.
