Aluminum Electrolytic Capacitors

Introduction

Aluminum electrolytic capacitors, as their name implies, are capacitors that contain an electrolyte, typically in the form of a liquid or some type of rubber or gel, between two aluminum plates. The electrolyte acts as an electron carrier, allowing the plates to store an electrical charge. The capacitance, or ability to store an electrical charge, of an aluminum electrolytic capacitor is based on the size of the aluminum plates, the kind of electrolyte used, and the area between the plates. This type of capacitor is widely used in a variety of electronic circuits.

EGPA350ELL472MM40S Application Field

The EGPA350ELL472MM40S aluminum electrolytic capacitor is a polarized, high-voltage, axial lead-type capacitor with a capacitance of 470µF and a voltage rating of 350V. It is manufactured with a conductive polymer aluminum electrolyte and is available in a variety of different termination styles.Due to its high voltage rating, the EGPA350ELL472MM40S is an ideal choice for applications in which the capacitor might be exposed to high voltage spikes or surges. It is commonly used in industrial equipment, such as motor starters, welders, and other high-voltage applications. Additionally, the EGPA350ELL472MM40S is also suitable for use in consumer electronics, such as in audio equipment, car stereos, and other AC/DC circuits.

Working Principle

An aluminum electrolytic capacitor works by storing an electrical charge on a series of aluminum plates. The liquid or gel electrolyte acts as an insulator between the plates, preventing the electric current from passing through. When a voltage is applied, the electrolyte allows an electric current to pass through the capacitor, allowing the plate to become charged.When the voltage is removed, the charged aluminum plates retain their stored electrical energy. This energy is then released back into the circuit when the capacitor is reactivated by reapplying the voltage. The magnitude of the energy stored in the capacitor is determined by the size of the aluminum plates, the type of electrolyte used, and the area between the plates.

Conclusion

The EGPA350ELL472MM40S aluminum electrolytic capacitor is a versatile, high-voltage capacitor used in a wide variety of consumer and industrial applications. Its polarization and voltage rating make it an ideal choice for scenarios involving high voltage spikes or surges, such as in motor starters, welders, and other high-voltage equipment. Through the use of aluminum plates and electrolytes, the EGPA350ELL472MM40S is able to store and release electrical energy, allowing it to act as an energy storage device in a variety of applications.
