Working Principle of UHE2A391MHD6

The UHE2A391MHD6 is a type of aluminum electrolytic capacitor. It consists of an aluminum can and two layers of metal pieces with the same area. Its working principle is based on the Faraday law of electrolytic conduction. The two metal pieces of the capacitor are firstly connected to power sources of different potentials, so that a current will flow. The metal pieces will build up charges of different signs. When these two metal pieces of the capacitor are connected to a dc power source, an electric field will form and create an electric potential difference. Under this electric field, the negative ions in the electrolyte will move towards the anode while the positive ions will move towards the cathode.

The electric current is electrical energy, while the accumulated charges in the capacitor constitute potential energy. The potential energy generated by the current flowing through the capacitor is called the electric potential. Once the capacitor is fully charged, the electric field disappears and the current will not flow. The aluminum can of the capacitor will keep the current and charges for a period of time and act as if electricity is stored in it. In conclusion, UHE2A391MHD6 is an aluminum electrolytic capacitor which is stable and reliable.
