• Industrial electronic systems
• Medical and healthcare systems
• Military and aerospace-grade systems
• Telecom and datacom systems
• Renewable energy systems

Working Principle

Aluminum electrolytic capacitors are based on a theory called Faraday\'s law of electrolysis. The law states that when a current flows through an electrolyte between two electrodes, the ions of dissolved salts will be attracted to one of the electrodes and cause a coating to form on that electrode. This coating is called the dielectric, and it takes the form of an oxide layer. In AECs, the anode is the aluminum foil, while the cathode is the oxide layer. This layer forms a polarized electric field, allowing the capacitor to store an electric charge.

The UPJ1K390MPD1TD AEC uses an improved dielectric layer called REFQU in order to improve its performance. REFQU is an electrolytically formed dioxide that has a higher dielectric constant than the traditional aluminum oxide layer used in other AECs. This gives the UPJ1K390MPD1TD AECs a higher capacity and longer service life.

The UPJ1K390MPD1TD AECs also use an improved cathode design to reduce the dissipation factor. Dissipation factor is the measure of how much of the energy stored in the capacitor is lost as heat. This is done by using a thicker anode plate and a graphite-coated cathode structure that helps to reduce the ESR levels and improve the performance.

Conclusion

UPJ1K390MPD1TD AECs are suitable for use in many application fields due to their high performance properties and long life performance. They are suitable for energy storage, buffering, filtering, and power conversion. The improved REFQU dielectric layer and improved cathode design give the UPJ1K390MPD1TD AECs a higher capacity and longer service life. By understanding the application fields and working principle of the UPJ1K390MPD1TD AECs, engineers and technicians can make better use of these components in their applications.
