Aluminum Electrolytic Capacitors

• MAL209436271E3 Application Field
  • MAL209436271E3, also known as an aluminum electrolytic capacitor, is a type of capacitor in which the anode is made of aluminum foil, a thin paper containing a dielectric material which is soaked in an electrolytic solution, and layers of a cathode foil and insulating material. It is typically used in applications such as electricity noise suppression, frequency compensation, decoupling, and ceiling voltage.
• MAL209436271E3 Working Principle
  • The primary function of the capacitor is to store electric charge, so it works by storing charge on the two conductive electrodes of the capacitor (the anode, which is made of aluminum foil, and the cathode, which is typically made of a different metal). A voltage difference between the two electrodes creates an electric field, which stores energy equal to the capacitance of the device multiplied by the square of the voltage applied. The electric field is also blocked from one of the electrodes, preventing the transfer of charge until the electric field is removed.
