Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components that store electrical charge between aluminum foils with an electrolyte instead of the common paper or plastic dielectrics used in most capacitors. They provide greater capacitance values than other capacitors in the same size, making them ideal for applications that require large amounts of capacitance in a small package. The UVR1H682MRD is an aluminum electrolytic capacitor from Nichicon that has a rated capacitance of 680 μF and is rated for 200 V. In this article, we will discuss the application field and working principle of the UVR1H682MRD.

Application Field

Aluminum electrolytic capacitors are widely used in electronic circuits because of their superior capacitance-to-size ratio. The UVR1H682MRD is often used on power lines to suppress high-frequency noise. As it can store more electrical energy than other types of capacitors, it is also used in applications that require energy storage, such as DC-DC converters, switch-mode power supply, and DC power supplies. Furthermore, due to its high capacitance, the UVR1H682MRD is also used to suppress electromagnetic interference in audio systems.

Working Principle

The UVR1H682MRD is an aluminum electrolytic capacitor with a polyethylene terephthalate (PET) dielectric and a liquid electrolyte. Aluminum electrolytic capacitors function by creating an electrical field between two conductive surfaces, in this case aluminum foil. The metal foil is then soaked in an electrolyte solution. The electrolyte functions as a conductor, allowing electrons to move between the two plates. This creates an electric potential between the two points, which can store electrical energy.The metal foil on one side of the capacitor is an anode, while the metal foil on the other side is a cathode. When an electrical charge is applied, positively charged ions in the electrolyte solution move towards the anode, while negatively charged ions move towards the cathode. This creates a field of charge, which is the capacitor’s electrical field. This field allows the capacitor to store energy, which can be used later.As a safety measure, the UVR1H682MRD is equipped with a discharge resistor that helps to safely discharge any excess energy stored in the capacitor. This helps prevent the capacitor from being damaged.In conclusion, the UVR1H682MRD is an aluminum electrolytic capacitor from Nichicon with a rated capacitance of 680 μF and is rated for 200 V. It is widely used in power lines to suppress high-frequency noise, DC-DC converters, switch-mode power supplies, and DC power supplies. It also works by storing an electrical potential between two aluminum foils soaked in an electrolyte solution. A discharge resistor is installed on the capacitor for safety.
