Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of polarized capacitor in which aluminum forms the plates and the two plates are separated by an electrolyte. They are widely used in electronics due to their relatively low cost, high capacitance values, low leakage, and robust design. The most common type of aluminum electrolytic capacitor is the radial-lead design, but there are also axial-lead and surface-mount versions available. In this article, we will focus on the EEU-FR1V182 application field and working principle.

EEU-FR1V182 application field

The EEU-FR1V182 aluminum electrolytic capacitor is a small, cylindrical aluminum capacitor designed for various applications. It consists of two aluminum foil plates separated by an electrolyte and can provide a capacitance range of 4.7uf to 3300µf. It has a rated voltage of 6.3 VDC to 50 VDC and a rated temperature range of -40 ℃ to +105 ℃, making it suitable for a wide range of applications. The EEU-FR1V182 is typically used for decoupling, filtering, and power supply purposes.

EEU-FR1V182 working principle

The working principle of the EEU-FR1V182 aluminum electrolytic capacitor is straightforward. When an electrical current is applied to the capacitor, it causes a chemical reaction in the electrolyte, causing the aluminum foil to form an insulating layer on the electrolyte between the two plates. This insulating layer acts as a dielectric, allowing the capacitor to store electrical charge. As the current continues to flow, the energy stored within the capacitor starts to increase, allowing it to store an even greater amount of energy for later use.

The EEU-FR1V182 aluminum electrolytic capacitor also has a self-healing mechanism that helps to protect against shorts, overloads, and current surges. This mechanism works by using a bleed resistor that is connected across the capacitor and acts as a fuse. If the capacitor is overloaded, the resistor will break down and the electrolyte within the capacitor will become conductive, allowing the excess electrical energy to dissipate harmlessly into the circuit.

In addition to its self-healing mechanism, the EEU-FR1V182 aluminum electrolytic capacitor also offers extended life, durability, and reliability. Its robust design and construction makes it well-suited for automotive, telecommunications, and other high-reliability application fields.

Conclusion

The EEU-FR1V182 aluminum electrolytic capacitor is a small, cylindrical aluminum capacitor used for power supply, decoupling, and filtering applications. It has a wide range of rated voltages from 6.3 VDC to 50 VDC and an extended life rating, making it ideal for a variety of applications. Additionally, its robust design and self-healing mechanism work together to provide an excellent level of protection, durability, and reliability.
