Introduction

Aluminum electrolytic capacitors, also known as aluminum electrolytic double layer capacitors, are self-healing many-layered devices with the ability to store electric charge. They have a wide range of applications, from low frequency AC/DC circuits to high frequency signals, and come in a variety of shapes, sizes and capacitance values to suit the job at hand. This article will discuss the application and working principles of the 100YXG680MEFC18X31.5 aluminum electrolytic capacitor.

Application Field of 100YXG680MEFC18X31.5

The 100YXG680MEFC18X31.5 capacitor is typically used in AC/DC convertor, communication circuit, power supply circuit, inverter circuits and other general-purpose applications due to its low ESR, low frequency losses, wide temperature range, wide voltage range and high capacitance-voltage characteristics. They can also be used in high power audio-visual equipment and other applications where temperature stability of the capacitance is important.

Working Principle of 100YXG680MEFC18X31.5

The 100YXG680MEFC18X31.5 capacitor is constructed from two aluminum foil layers sandwiched between two layers of an electrolyte. The two layers of aluminum foil are polarized with one layer being an anode and the other a cathode, and the two layers of electrolyte serve as a dielectric medium. When voltage is applied to the two layers of aluminum foil, electrochemical reactions occur at both of the electrodes resulting in the aluminum foil and the electrolyte becoming charged. This charges up the capacitor and allows it to store energy. When the voltage is removed, the aluminum foil and electrolyte shrink back to their original state, thus releasing the stored energy.

Conclusion

In conclusion, the 100YXG680MEFC18X31.5 aluminum electrolytic capacitor has a wide range of applications, from low frequency AC/DC circuits to high frequency signals, and is suitable for use in high power audio-visual equipment and other applications where temperature stability of the capacitance is important. Its working principle is based on electrochemical reactions which allow the two aluminum foil layers to charge up and store energy, which can then be released when the voltage is removed.
