Aluminum Electrolytic Capacitors: UVZ1H472MRD Application Field and Working Principle

Aluminum electrolytic capacitors are important and indispensable components of traditional electronics. In many applications, aluminum electrolytic capacitors are essential for providing electrical energy or power storage capacity and power filtering requirements. As one of the most commonly used aluminum electrolytic capacitors, the UVZ1H472MRD needs to be further discussed in terms of application field and working principle.

Application Field of UVZ1H472MRD

The UVZ1H472MRD is a type of miniature aluminum electrolytic capacitors. It was typically designed as a radial, non-solid electrolyte, and is typically provided in two versions, vertical and horizontal types, with a diameter of 6MM and height of 7.3MM. The maximum rated voltage for the UVZ1H472MRD is 35V. The UVZ1H472MRD capacitor has a maximum ripple current rating of 1.14A, with short circuit current of 500mA. Its ripple current depends on the rated voltage and the capacitance value. The UVZ1H472MRD capacitor is widely employed as a replacement for film capacitors as it generally offers lower ESR and higher capacitance densities. Its application fields include power supplies, automotive electronics, power management, audio and switching power supplies, as well as computers, audio/video equipment, SMPS, DC/DC converter and more.

Working Principle of UVZ1H472MRD

An aluminum electrolytic capacitor is an electronic component package consisting of in two aluminum foil sheets that form the electrodes and a separator sheet with an electrolyte, then rolled up and enclosed in a protective case. When the capacitor is connected in a circuit, electrons form an electric field through the device, and the electric field created by the electric charges induces a screening electrical field. This screening together with the dielectric work to keep the two aluminum foils separate yet interrelated. The operation of the UVZ1H472MRD capacitor is nothing more than the application of these basic principles. In terms of its principle of operation, when an alternating voltage is applied to the capacitor it will draw a current, but this current will be limited due to the resistance of the capacitor. This property is called the capacitor\'s impedance, which is determined by the ratio of the maximum charge stored to the peak current supplied. The higher the capacity of the UVZ1H472MRD capacitor, the lower its impedance and therefore the higher the current drawn. This higher current then helps to increase the storage capacity of the capacitor by further storing energy in it when the voltage is applied.

Conclusion

The UVZ1H472MRD aluminum electrolytic capacitor is one of the most commonly used types of aluminum electrolytic capacitors, and it\'s finding its use in a wide range of applications. The UVZ1H472MRD capacitor has a maximum ripple current rating of 1.14A, with short circuit current of 500mA, and the principle of its operation is determined by the ratio of the maximum charge stored to the peak current supplied. As aluminum electrolytic capacitors such as the UVZ1H472MRD are essential components for many applications, understanding their application fields and working principles are important in order to properly utilize these components.
