Aluminum electrolytic capacitors are commonly used in many electrical applications due to their size, high capacitance values, and low cost. The UVZ1C470MDD is a particular type of aluminum electrolytic capacitor advantageous for higher voltage applications. This type of capacitor offers an extremely high volumetric efficiency and low equivalent series resistance (ESR), making it an ideal choice for applications where high levels of reliability are needed. This article will discuss the particular application field and working principle of the UVZ1C470MDD.

Application Field

The UVZ1C470MDD aluminum electrolytic capacitor is typically used in audio and video equipment, computers, and other digital electronics. Its wide temperature range (-40°C to +105°C) and long life makes it a popular choice for these applications. It is also used in portable devices, such as cell phones and digital cameras, where reliability is paramount. Additionally, the UVZ1C470MDD offers a high ripple current capacity, making it well-suited for applications that require high peak currents, and its very low ESR makes it suitable for switching power supplies.

Working Principle

The UVZ1C470MDD aluminum electrolytic capacitor consists of two electrodes divided by a dielectric layer of electrolyte. The capacitance is determined by the area of the electrodes, the thickness of the dielectric, and the type of electrolyte material. The electrodes in the UVZ1C470MDD are made from aluminum foil which is oxidized to increase the dielectric\'s surface area, and the dielectric is filled with an organic electrolyte called ethylene glycol. This oxidation process also forms a thin insulating layer on the surface of the aluminum which prevents short circuits. The electrolyte layer breaks down over time due to the electrolysis, reducing the capacitance and increasing leakage current.

The UVZ1C470MDD capacitor is an advantageous device because of its high volumetric efficiency, which allows it to contain more capacitance per unit volume, and it has low ESR due to its high dielectric strength. As a result, it can withstand greater voltage and offers greater reliability. It also has a very low leakage current and is resistant to high temperatures and mechanical shock and vibration, making it suitable for a variety of applications.

Conclusion

The UVZ1C470MDD aluminum electrolytic capacitor offers many advantages for applications that require reliable and high voltage operation. Its volumetric efficiency allows it to contain more capacitance in a smaller package, and its low ESR ensures reliable operation. Furthermore, it has a wide temperature range and excellent resistance to mechanical shock and vibration. As a result, the UVZ1C470MDD is a popular choice for portable devices, computers, and other digital electronics.
