ULD2G4R7MPD Application Field and Working Principle

ULD2G4R7MPD aluminum electrolytic capacitors are mainly used in power electronics fields such as control circuit, connection circuit, LED drive power supply, constant voltage/current source, active power filters, transmission & distribution, switching power supply, digital and analog circuit, etc. It can be used when the temperature is between +85°C to -55°C.

The working principle of the ULD2G4R7MPD aluminum electrolytic capacitor is related to the principle of electrolysis. In terms of composition, it consists of a positive pole and a negative pole separated by an electrolyte. Generally speaking, the positive pole is an aluminum foil (aluminum sheet) brought into contact with an electrolyte, and the negative pole is an oxide film formed on the surface of the aluminum sheet. When a DC voltage is applied, a Faraday separation of charges occurs, and an oxide film with a thickness of about 3 nanometers is formed on the surface of the aluminum sheet, forming a capacitor.
