Aluminum electrolytic capacitors are very common in the industry due to their low cost, large capacity, and long service life. The 400KXF100MEFCSN25X20 aluminum electrolytic capacitor is a particular type of capacitor that is ideal for applications in various fields and electronics. This guide explains the application fields and working principles of this specific capacitor.

What is an Aluminum Electrolytic Capacitor?

An aluminum electrolytic capacitor is a type of electrochemical capacitor, which is made of two aluminum foils that are separated by a permeable material which is soaked in an electrolyte. When a voltage is applied the electrolyte films over the aluminum foils indicating an electrically polarized interface and a capacitance is created. Aluminum electrolytic capacitors have very high capacitance for their size and are widely used in consumer products and industrial applications where a small size and low cost are preferred. Their long-service life and solid construction make them ideal for demanding environments.

400KXF100MEFCSN25X20 Application Field and Working principle

The 400KXF100MEFCSN25X20 aluminum electrolytic capacitor is a large format capacitor with an estimated capacitance of 400 µF at a working voltage of 25 V. This particular capacitor is well suited for various applications including: automotive ignition, air conditioner power supply, LED power supplies, and heavy industrial equipment. Due to their low cost and large capacity, they are often used in applications where higher-end components may not be available or too expensive.

The working principle of the 400KXF100MEFCSN25X20 capacitor is based on the principle of electrochemical polarization. When an external electric field is applied across the capacitor, a shift of charges through the oxide layer occurs, setting up a current that flows between the two plates. This reaction produces a polarized potential difference between the plates resulting in a series of alternate oxidized and reduced layers that act as the double layers or capacitive plates. The capacitance of the 400KXF100MEFCSN25X20 capacitor is determined by its surface area, as well as its working voltage.

Conclusion

The 400KXF100MEFCSN25X20 is a large-capacity and low-cost aluminum electrolytic capacitor which has a variety of applications in the industrial, automotive, and consumer electronics fields. Its working principle is based on electrochemical polarization and its capacitance is dependent on the working voltage and surface area. Hopefully this guide has provided a short explanation of the working principle and applications of the 400KXF100MEFCSN25X20 aluminum electrolytic capacitor.
