Introduction

Aluminum electrolytic capacitors are a type of capacitor made of aluminum foil and insulated by a film of solid electrolyte. It works by utilizing the electrolytic action between the two oppositely oriented aluminum plates. The electrolyte serves to improve the performance of the aluminum by providing a wider surface area for storage of electric charge. In this article, we will go over the application fields and working principle of UVR1V682MRD capacitors.

Application Fields

UVR1V682MRD capacitors are mainly used for high-frequency pulse power applications. This includes applications such as power filters and frequency synthesizers. Because of the wide range of electrical and physical properties, these capacitors are also useful for high-speed signal processing, power conditioning and clamping, and in microcontrollers. They are also used in electronic fuel injectors and various other combustion applications.

Working Principle

UVR1V682MRD capacitors are divided into two parts: the anode and the cathode. In this configuration, the anode is made of aluminum foil, while the cathode is made of a solid electrolyte film. When a voltage is applied to the capacitor, the positively charged anode and negatively charged cathode create an electrical field. This electrical field induces an electric current to flow between the plates, which in turn charges the capacitor.When the capacitor is discharged, the electric field is reversed and the charges on the two plates are depleted. The depletion of the electric charges creates a voltage drop across the capacitor. This voltage drop is an indication of the capacitor’s storage capacity and is commonly referred to as the “cutoff voltage” of the capacitor.

Conclusion

UVR1V682MRD capacitors are a type of aluminum electrolytic capacitor, used for high-frequency pulse power applications such as power filters and frequency synthesizers. The working principle of these capacitors involves the utilization of an electrical field induced by two oppositely oriented aluminum plates to charge and discharge the capacitor. The cutoff voltage of the capacitor is an indication of its storage capacity.
