Introduction of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are passive electronic components which are required in a wide range of applications. This type of capacitors are formed by attaching two aluminum foils with an insulating material in between. The electrolyte serves as the second plate of the capacitor through which electrical current can flow. It is usually composed of organic solvents, gelling agents, and additives. Aluminum electrolytic capacitors are designed to provide long-term capacitive and conductive properties.

ALS71U622NF450 – Field of Application and Working Principle

The ALS71U622NF450 is a small sized radial-leaded aluminum electrolytic capacitor, mainly used as a power supply filter in A/C drives and is specially developed for uninterruptable power supplies. The electrolyte contained in an aluminum electrolytic capacitor is the source of the capacitance. An electric current is created in the aluminum anode of the capacitor when two electrodes are connected to a battery or power source. The current then creates a charged layer of electrons on the surface of the anode, which forms an electric charge with the reverse charge on the electrolyte plate. The capacitor will then hold a certain voltage until a certain current is applied to it.These capacitors have a much larger capacitance than other types of capacitors, and this is because they use the electrolyte as a dielectric material. The higher the dielectric constant of the electrolyte, the greater the capacitance of the capacitor. The higher dielectric constant of the electrolyte also has the advantage of allowing for smaller size capacitors while retaining the same capacitance.The ALS71U622NF450 also has an extended temperature range, making it suitable for industrial applications. It has an operating temperature range from -55°C to +85°C and can be used in high temperature environments such as in automotive, military and aerospace applications. The extended temperature range also allows for increased stability in the operation of the capacitor.The ALS71U622NF450 has also been designed with an extended lifetime, making it suitable for use in long-term applications. Its self-healing property helps the capacitor to maintain a stable voltage even after a large surge of electrical current. This helps to protect the components that the capacitor is connected to and reduce the need for unscheduled maintenance and replacement.

Conclusion

The ALS71U622NF450 aluminum electrolytic capacitor is a small sized, radial-leaded type capacitor which is mainly used as a power supply filter in A/C drives and uninterruptible power supplies. It has an extended temperature range, allowing it to be used in high temperature environments as well as an extended lifetime, making it suitable for long-term applications. Its electrolyte is the source of the capacitance, providing a high capacitance and dielectric constant allowing for smaller size capacitors with more stable operation.
