Working Principle of UPA1E681MPD1TD

UPA1E681MPD1TD aluminum electrolytic capacitors are non-polarized capacitors that use an aluminum oxide-coated anode foil forming the dielectric which is enclosed in a vacuum or gas-filled tube with a cathode foil and a liquid electrolyte. The cathode exposed tab is connected to the large aluminum plate, which is separated from the anode plate by the dielectric material. When external DC voltage is applied, it causes the positive ions in the electrolyte to attract the electrons from the cathode foil and flow through the dielectric material to the anode plate. This flow of ions forms a conductive path and charges the aluminum plate with electrons. At the anode, the electrons recombine with the ions in the electrolyte and the energy is store in the capacitor.

The capacitor also reverses the charge process when the voltage is reversed, releasing the energy stored in the capacitor in the form of current.This process of charging and discharging gives rise to the capacitance value of the device, which is determined by the total area of each aluminum plate in the aluminum electrolytic capacitor.
