Aluminum Electrolytic Capacitors are capacitors with an electrolytic solution with an anode made of a metal foil, covered with an insulating oxide layer. UFW1V682MRD is a type of aluminum electrolytic capacitor.

Application Field

UFW1V682MRD aluminum electrolytic capacitors are mainly used in automotive, consumer electronics and industrial power supply applications. For example, in modern home theater systems and car audio systems, they are used in the power supply circuit to filter fluctuations in the main power source. UFW1V682MRD capacitors are also used in LED lights for indoor and outdoor illumination, industrial electronic circuits for temperature regulation, detector circuits and medical monitoring equipment.

Working Principle

The principle of operation of UFW1V682MRD aluminum electrolytic capacitors is similar to that of film capacitors. The source of the capacitance is an oxide layer formed on the surface of a high purity aluminum foil. The oxide layer is formed by passing a direct current through the aluminum foil, which oxidizes the aluminum and forms a thin, insulating layer on the surface of the foil. The cathode material is made up of a metallic electrolyte, which is often a solution of boric acid, or other chemical compounds, that maintain the capacitance while providing thermal stability.

The electrolyte also serves as a conductor between the anode and the cathode, allowing electric charge to travel between them. The electric current is carried through the oxide layer by the ions of the electrolyte, while electrons move through the oxide layer as an electrical charge. The oxide layer prevents the anode material from being oxidized, thus allowing the capacitor to retain its capacitance for a long time.

UFW1V682MRD capacitors have improved endurance and are reliable and robust. They are designed to operate at a wide temperature range, ranging from -40°C to +125°C. Due to the high levels of capacitance and voltage ratings, UFW1V682MRD capacitors are ideal for industrial, automotive, and consumer electronic applications.
