Working Principle of EKMS451VSN221MQ40S

Aluminum electrolytic capacitors are fundamentally different from other types of capacitors, as they contain an electrolyte, typically a mixture of ionic salts and organic solvents. This electrolyte increases the dielectric constant of the aluminum oxides, allowing greater capacitance on a smaller footprint.

In the case of the EKMS451VSN221MQ40S, two layers of aluminum oxide dielectric are formed through anodic oxidation, and a separator impregnated with the electrolyte is then sandwiched between them. When a voltage is applied, electric current flows through the electrolyte, resulting in an electric field between the two oxide layers. This electric field creates a capacitance that is proportional to the area of the oxide layers, the distance between them, and the dielectric constant of the electrolyte.

The electrolyte of the EKMS451VSN221MQ40S is hermetically sealed within the capacitor, preventing any leakage and therefore ensuring reliable performance. This makes the EKMS451VSN221MQ40S a particularly suitable choice for use in high-voltage electrical systems.

Conclusion

The EKMS451VSN221MQ40S is an aluminum electrolytic capacitor, widely used for a variety of applications due to its versatility and reliable performance. Its application fields include power electronics, RF, and industrial use, while its working principle is based on an anodically formed dielectric layer of aluminum oxide, plus an internal electrolyte that holds the electric charge.
