Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electronic capacitors, are energy storage components that use electrochemical reactions between two metal electrodes with an electrolyte to store electrical charge. Among the various types of capacitors, aluminum electrolytic capacitors are the most widely used and have advantages in terms of cost and size. In addition, the aluminum electrolytic capacitor can also have a large capacitance for a given size, so it is often used in filters, power supplies, signal coupling, bypass and energy storage.

The EEU-FS1H122 aluminum electrolytic capacitors combine a low ESR, low leakage current and high capacitance in one package. This series of capacitors is ideal for power supply applications that require performance above standard levels. In addition, the EEU-FS1H122 series of aluminum electrolytic capacitors has a wide temperature range and excellent surge characteristics, making them suitable for severe environments.The applications for the EEU-FS1H122 aluminum electrolytic capacitors include: power supplies, solar and telecommunications, automotive, lighting control systems, medical and audio-visual equipments, and more.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on electrochemical reactions between two metal electrodes and an electrolyte. An electrolyte is an ionic conductor, which can generate a charge exchange between the two metal electrodes.The positive and negative electrodes of the capacitor contain an anode and a cathode, respectively. The anode is made of aluminum foil. The cathode is made of a material with excellent chemical and electrical properties (for example manganese dioxide), which is etched on both sides of the aluminum foil as a capacitor dielectric material.When a potential difference is applied between the anode and the cathode, the electrolyte acts as a bridge between the two electrodes, allowing an electric current to flow. As more charges build up on the two electrodes, an electric field is formed, which leads to an accumulation of electric energy. This electric energy is stored in the capacitance.The capacitance of the aluminum electrolytic capacitor is determined by the total area of the electrodes, the distance between the two electrodes, and the dielectric constant of the electrolyte. The higher the capacitance, the more electric energy can be stored in the capacitor.

Conclusion

The EEU-FS1H122 aluminum electrolytic capacitors are ideal for power supplies and other applications that require higher performance levels. The capacitors are small in size, have high capacitance and low ESR, and have excellent surge characteristics. The working principle of an aluminum electrolytic capacitor is based on electrochemical reactions between two metal electrodes and an electrolyte. The capacitance of the aluminum electrolytic capacitor is determined by the total area of the electrodes, the distance between the two electrodes, and the dielectric constant of the electrolyte.
