Aluminum Electrolytic Capacitors

The EEU-FR1V471B is a highly versatile type of aluminum electrolytic capacitor (AEC) that is used in a variety of applications. AECs are highly reliable and cost-effective components that are used in various types of circuits ranging from analog applications to digital applications. Moreover, they are used in various types of power supplies, ensuring stable levels of power to devices and components.

An EEU-FR1V471B is an aluminum electrolytic capacitor with a miniature, 4-terminal package that enables use in small size and space-constrained applications. It has a rated voltage of 4V, and its main advantages include excellent noise characteristics, low ESR, and low DF. Additionally, it features low impedance over a wide temperature range and a long life with high ripple current capability.

The basic principle of aluminum electrolytic capacitors is its ability to store energy by using an electrolytic medium. This medium is an arrangement of two plates separated from each other with some gap, which will form the insulating material. When a voltage is applied across both ends of the capacitor, a charge will start to build up on each plate, one being positive and the other negative. Through this electrical energy, a magnetic field is created between the two plates.

In AECs, the plates are made out of aluminum and are often coated with a thin layer of metal oxide to provide the insulation. This metal oxide layer also acts as a dielectric material and dissipates heat. The foil electrodes are commonly made of metal alloys like manganese and silver. The electrodes are then connected to the negative and positive terminals of the capacitor, thus completing the circuit.

It is important to note that the dielectric layer must be intact and undamaged in order to ensure effective conduction and long-term durability. In the application of AECs, the choice of ESR should be based on the power supply, operating voltage, and current load.

The application fields of EEU-FR1V471B aluminum electrolytic capacitors are wide and varied. The most common use for the component is for filtering, decoupling, and noise suppression in power supplies. It is also used for power supply stabilization, voltage equalization, and ripple absorption in various types of circuits. Additionally, it is used in power switching converters, motor drives, and electrical chargers.

The working principle of EEU-FR1V471B aluminum electrolytic capacitors is relatively simple. When a passing current is applied, charge builds up on two metal plates that act as an electrical insulator. This insulator is the dielectric material, which dissipates heat and provides the necessary insulation. As the current passes through the capacitor, the metal plates create a magnetic field, which stores electrical energy.

As charge continues to build up, the metal plates will become increasingly saturated and start to store more electrical energy. When the current decreases, the stored electrical energy will slowly decreases and is released. This is why aluminum electrolytic capacitors are essential components for regulating and stabilizing power supplies.

EEU-FR1V471B aluminum electrolytic capacitors are vital components for modern electrical and electronic systems. They are highly reliable and affordable, making them popular for a wide range of applications. These capacitors offer excellent performance in a variety of circuits and guarantee safe operation in both analog and digital systems.
