Working Principle

The 381LX680M400J012 aluminum electrolytic capacitor utilizes the principle of capacitive reactance. This capacitor is made up of two aluminum foils enclosed in an electrolyte solution. The two foils are separated by an insulating material, such as paper, mica, or Teflon. When an electric potential is applied, as occurs in a circuit, a current flows between the two aluminum foils. The current moving through the electrolyte solution generates an electric field, which causes the charge on the two foils to become distributed differently. This difference in charge creates a capacitance, which stores energy and can be used to supply current.
