Aluminum Electrolytic Capacitors (AEC) are devices that store electrical energy within an aluminum or tantalum electrolyte. AECs are used as storage devices for power supplies and electronic circuitry, due to their high capacitance and long life.

The EEE-FK1C681AP is an Aluminum Electrolytic Capacitor rated for a 6.3V DC with high temperature range. This particular AEC is a non-polarized, low impedance device designed for the applications such as high frequency switching power supplies, audio equipment, and numerous other high-frequency, high-current applications. It has a capacity of 680 µF and a low ESR (Equivalent Series Resistance) of 9 mOhm, which offers stable capacitive performance under high frequency usage.

In terms of the application field, the EEE-FK1C681AP is ideally suited for systems where the performance and efficiency are of the utmost priority, such as UPS, solar power inverters, computer mainboards and power supplies. Furthermore, in audio applications, this capacitor can help filter a signal, which improves the clarity of sound.

The working principle of AECs is based on Faraday\'s law of electrolysis, which states that the quantity of electric charge involved in a given process is directly proportional to the difference in potential between the start and end states of the process. In other words, when current passes through an electrolytic solution, it results in the formation of two electrodes, thus creating a capacitor. This is how an AEC operates, with the positive electrode being the anode and the negative electrode being the cathode.

This particular capacitor also uses an anode made from aluminum with a thin oxide layer, along with a liquid electrolyte containing anions that flow from the anode to the cathode, thus forming an electric double layer. This layer is composed of positive ions on the anode and negative ions on the cathode and is responsible for producing significant capacitance.

To sum it up, the EEE-FK1C681AP aluminum electrolytic capacitor is a high performance, low impedance device that is suitable for numerous high-frequency, high-current applications. It has a long life and high capacitance, making it an ideal option for power supplies, audio equipment, and solar power inverters, as well as many other systems where performance and efficiency are imperative.
