Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various fields due to their advantages such as high volumetric efficiency, large capacity, low cost and easy installation. The most important feature of aluminum electrolytic capacitors is the superior combination of high capacitance and low equivalent series resistance (ESR). This type of capacitor is used for AC applications, DC applications, signal applications, and power management.

EEU-ED2D470 Application Field and Working Principle

EEU-ED2D470 aluminum electrolytic capacitors are classified as a general-purpose capacitor with a size of 10x25mm. The EEU-ED2D470 capacitor is mainly used for personal computers, consumer electronics, automotive electronics, industrial applications, and power supplies. They are available in 4V-450V and 470μF-5000μF capacitance range, and are RoHS-compliant.

EEU-ED2D470 capacitors employ a rolled anode structure with an anode-electrolyte gap. The outer body of the capacitor is made of aluminum housing, and there is a silver-plated aluminum foil sheet inside the housing. This increases the mechanical strength of the capacitor. The capacitor also has four rubber brackets, two plastic poles, and paper to prevent short circuits.

The working principle of the EEU-ED2D470 capacitor is that when a voltage is applied to the device, electrons will be attracted to the anode, which will create a positive charge on the anode and a negative charge on the cathode. This creates an electric field across the anode-electrolyte gap, where ions from the electrolyte travel to the anode and cathode, creating a current. The electrons travel to the capacitor\'s anode plate, creating a capacitance field across the anode-electrolyte gap.

A capacitor\'s capacitance is a measure of the amount of electrical charge stored in it. As the voltage applied to the EEU-ED2D470 capacitor increases, the capacitance increases, and as the voltage decreases, the capacitance decreases. The capacitance is determined by the size of the anode-electrolyte gap, as well as the materials used in the construction of the capacitor. By increasing the size of the gap and/or using materials with higher dielectric constants, the capacitance of the capacitor can be increased.

The EEU-ED2D470 capacitor is extremely suitable for high-current applications due to its low ESR (equivalent series resistance) value. The lower the ESR, the better the capacitor\'s performance and the higher current it can handle. The EEU-ED2D470 capacitor offers excellent temperature stability, making it suitable for use in extreme temperature environments.

In conclusion, the EEU-ED2D470 aluminum electrolytic capacitor is an excellent choice for a variety of applications, such as power management, automotive electronics, industrial applications, consumer electronics, and personal computers. The EEU-ED2D470 capacitor offers excellent performance, reliability, and temperature stability, making it suitable for a wide range of applications.
