Aluminum electrolytic capacitors, known as aluminum electrochemical capacitors, “electrolytic capacitors” or “electrolytic paper”, are the most commonly used capacitors in electronic products. ELXQ351VSN821MA50S is a kind of aluminum electrolytic capacitor.

An aluminum electrolytic capacitor is an electronic component that combines the functions of both capacitors and electrolytic cells, that is, it acts as both an energy storage device and an electrolytic cell. It uses chemical reaction in a special electrolyte and an oxide film formed on the surface of an aluminum electrode material to store energy.

ELXQ351VSN821MA50S is an aluminum electrolytic capacitor mainly used for UPS uninterruptible power supplies, switching power supply, converter, frequency conversion equipment, energy storage equipment and other fields. It has the characteristics of low equivalent series resistance (ESR), low equivalent series inductance (ESL) and very low leakage current, which make it worth using in low leakage current requirements occasions.

When the ELXQ351VSN821MA50S capacitor is in use, the positive terminal of the power supply is connected with the positive electrode of the aluminum electrolytic capacitor, and the negative terminal of the power supply is connected with the negative electrode. The working principle of the aluminum electrolytic capacitor is to use an aluminum foil as a cathode with a thin oxide film formed on the surface, separated by a liquid electrolyte. When the capacitor is in a charging state, a potential is generated on both sides of the aluminum foil due to the electrochemical reaction, which causes electrons to flow to the anode. This electron current charges the capacitor until it is saturated. When a reverse voltage is applied, the oxide film is broken, and the liquid electrolyte conducts electrons, so that the energy stored in the capacitor is released.

In summary, ELXQ351VSN821MA50S is an aluminum electrolytic capacitor, mainly used for UPS uninterruptible power supply, switching power supply, converter, frequency conversion and energy storage equipment. Its main features are low equivalent series resistance (ESR), low equivalent series inductance (ESL) and very low leakage current. When in use, the positive and negative terminals of the power supply are connected with the positive and negative electrodes of the aluminum electrolytic capacitor, respectively. When charging and discharging, the electrochemical reaction occurs, which is the working principle of the aluminum electrolytic capacitor.
