This type of aluminum electrolytic capacitor also has a wide range of operating temperature ranges, so it can be used in applications where temperatures may vary.

Working Principle

The EEU-FS1A122B aluminum electrolytic capacitor is a type of electrolytic capacitor that uses an anode made of aluminum foil and a cathode made of porous carbon or a combination of aluminum foil and manganese dioxide. It is composed of two metal foil electrodes, insulation paper and liquid electrolyte. The operation of the aluminum electrolytic capacitor works by having an anode with a thin polymer layer that electrostatically attracts the electrolyte, which facilitates the storage of electric charge.

When an electric current is passed through the aluminum electrolytic capacitor, the electrolyte around the anode expands and forms a thin, conductive layer. This thin and conductive layer causes the capacitance of the capacitor to increase. As the current increases, the charge on the capacitor continues to accumulate and the capacitor charges and discharges quickly in the range of tens of microseconds, allowing for very fast charging and discharging.

The aluminum electrolytic capacitors can store energy at the highest energy density compared to other types of capacitor technologies. This makes them good choices for applications where large amounts of energy need to be stored in limited space. Additionally, aluminum electrolytic capacitors have a longer life expectancy compared to other types of capacitors, which is one of the main reasons why they are frequently used in many applications.

In conclusion, the EEU-FS1A122B aluminum electrolytic capacitor is a popular type of electrolytic capacitor used in various applications. Its application field includes audio and video systems, instrumentation, communications systems and various industrial equipment. The working principle of the EEU-FS1A122B aluminum electrolytic capacitor is based on the electrostatic attraction of the electrolyte on the anode, which together help to increase the capacitor\'s capacitance. Additionally, the aluminum electrolytic capacitor has a higher energy density, longer life expectancy and relatively fast charging and discharging rate, making it a great choice for various applications.
