Additionally, it can be used in audio power amplifiers, sound box and other high-power sound devices.

Performance Characteristics of UPZW6390MHD

The UPZW6390MHD aluminum electrolytic capacitor features high temperature endurance, high ripple current capacity and excellent electrical performance. It has a rated copper foil thickness of 0.35mm and a rated copper foil width of 20mm with a rated voltage of 230V. It also has an ambient temperature of 105°C, ripple current of 300mA and is rated for capacitance of 47UF. The capacitor offers a good combination of size and performance for a variety of applications.

Working Principle of UPZW6390MHD

Aluminum electrolytic capacitors are constructed with a thin aluminum foil covered on the outside with an electrolytic material and wound into a stack. The capacitor is then sealed in a plastic container. The inside is filled with an electrolyte. An electric current then flows through the electrolytic material and forms a thin layer of oxide on the aluminum, increasing the surface area and forming a dielectric between the two poles. This allows the capacitor to store electrical energy as a potential difference between the two poles. The UPZW6390MHD capacitor uses an accurate anode foil to improve the stability and leakage of the capacitor. The aluminum dual anode foil has two layers of anodes, one anode having a standard capacitance, while the other has a heavier capacitance, improving the stability of the device by using the additional capacitance to compensate for the variations in materials and environment.

Conclusion

The UPZW6390MHD aluminum electrolytic capacitor is an excellent option for various power supply applications, including audio power amplifiers and sound boxes. It offers great performance, stability and reliability with a combination of size and performance for a variety of applications. Furthermore, its working principle of using an aluminum dual anode foil ensures the device will have improved stability and leakage characteristics, making it a great option for many applications.
