Working Principle of UTT1C151MPD1TA

The UTT1C151MPD1TA aluminum electrolytic capacitor is composed of four layers: central steel core, anode aluminum foil, diaphragm and cathode lead plate. The formation of capacitance is related to the distance between the two plates. The closer the distance, the greater the capacitance.

In order to increase the density between aluminum foil and diaphragm, the electrolyte is added to form an oxide film on the surface of aluminum foil to increase its voltage resistance and reduce the equivalent series resistance of aluminum electrolytic capacitor.

The specific working principle is as follows. When a voltage is applied between the two electrodes (anode and cathode) of the aluminum electrolytic capacitor, it will cause an electric current to flow through the electrolyte and form an oxide film on the surface of the cathode. The oxide film can be regarded as an insulating layer, and the charge can be stored on the two electrodes.

When the external voltage circuit is disconnected, the charge on the two electrodes will continue to exist due to the effective insulation of the oxide film, and the electrical energy conversion will be stored in the form of electrostatic energy in the capacitor.

Al oxide film and electrolyte play an important role in the working principle of aluminum electrolytic capacitor, which can reduce equivalent series resistance, increase capacitance conversion efficiency and promote slow transmission in voltage compensation.
