Aluminum electrolytic capacitors are widely used components which store electrical energy and provide power delivery when needed. The model ELXM351VSN391MA35S is no exception. This article will provide information on its application field and working principles.

Application Field

The ELXM351VSN391MA35S are aluminum electrolytic capacitors designed for medium and low-voltage switchgear power supply devices. The capacitors use high-voltage, rated voltage between 10 kV and 35 kV, and are compliant with and certified to GB4343-2007 and GB/T13464.1-2007 standards, respectively. This makes them ideal for use in a variety of DC and low-voltage AC applications, both in domestic and industrial environments.

The connectors used are of screw-down type, which are designed to withstand high temperatures and long-term operation. The capacitors have a capacity of 95 Farads and a sintering resistance of less than 0.45 ohms. They are also insulated with polypropylene film for extra protection. The capacitors are relatively small in size and light in weight, allowing them to be easily installed.

Working Principle

Aluminum electrolytic capacitors use an electrolyte as the dielectric and a porous layer of aluminum oxide to produce a capacitance. They are generally referred to as “non-polarized” capacitors, as they allow the current to flow in only one direction. This is due to the fact that a layer of oxide is formed over the aluminum plates inside the capacitor, thereby blocking any attempt to flow in the opposite direction.

Under low voltage, the capacitors are used for basic filtering and signal application. Under high voltage applications, the capacitors are designed to withstand high-frequency energy, providing crucial smoothing and buffering between the incoming power supply and the load. The capacitors also protect the load from voltage spikes and excess current.

The ELXM351VSN391MA35S capacitors work in a similar manner. When a voltage is applied to the capacitor, it stores the electric charge in the form of a potential difference between two electrodes. This electric charge can then be delivered to the load whenever necessary. Additionally, the capacitors also block any attempt to flow electricity in the opposite direction.

Conclusion

In conclusion, the ELXM351VSN391MA35S aluminum electrolytic capacitors are specially designed for medium and low-voltage switchgear power supply devices. They are relatively small, lightweight and easy to install, while their certified ratings make them suitable for a variety of industrial applications. The capacitors store the electric charge between two electrodes and deliver it to the load whenever needed, while blocking any attempts to flow in the opposite direction.
