Aluminum electrolytic capacitors (typically referred to as electrolytic capacitors) are one of the most common types of capacitors that incorporate a non-solid electrolyte like an alkaline or aqueous solution as an intervening medium to form an electric double layer at an electrode’s surface. The most popular type of these capacitors are the Radial Aluminum Electrolytic Capacitors and the ERHB631LGC332MFC0U model is one of them.

Application Fields

Radial Aluminum Electrolytic Capacitors, like the ERHB631LGC332MFC0U model, are used in a wide range of applications such as motor drives, power supplies, audio equipment, and consumer electronics. In addition, these capacitors are designed to provide a low equivalent series resistance (ESR) and self-healing properties. They provide highly reliable, long-term operation in applications requiring stability with minimal time-temperature drift. Furthermore, these capacitors can bear up to 105℃ of ambient temperature and can be used in surge current applications where high frequency oscillations are expected.

Working Principle

The working principle of an Radial Aluminum Electrolytic Capacitor revolves around the fact that it consists of two metal foils that are separated by a liquid electrolyte. An electrical current is applied across the positive electrode (anode) and the negative electrode (cathode) of the capacitor, where the anode foil is made of aluminum oxide and the cathode foil is made of aluminum. These two electrodes are separated by a dielectric material like paper or plastic. The electric charge gathered on the electrodes creates an electric field between them, leading to the polarization of the electrolyte. The amount of electric charge that can be stored depends on the amount of electrolyte that is present between the two foils.

The electrolyte acts as a conductive medium, allowing the electric current to pass through it and giving the capacitor its self-healing properties. This is because when the capacitor is subjected to a surge in electric current, the electrolyte breaches the dielectric material separating the anode and the cathode in order to make up for the extra current. This reduces the amount of charge stored on the plates and keeps the capacitor from suffering any lasting damage. This phenomenon is known as crystallization and is one of the key advantages of aluminum electrolytic capacitors over other types of capacitors.

Conclusion

The Radial Aluminum Electrolytic Capacitor ERHB631LGC332MFC0U has a wide range of applications and is suitable for use in various industrial and consumer applications. Its self-healing properties make it an ideal choice for applications that involve sudden surges in electric current. These capacitors provide long-term operation in applications involving stability with minimal time-temperature drift and can bear up to 105℃ of ambient temperature.
