The LPW153M1AN35V-W is suitable for use in temperatures ranging from -40℃ to +105℃ and temperatures up to +125℃ for a short period of time.

Working Principle

An aluminum electrolytic capacitor is composed of a number of layers of alternating aluminum and paper that are assembled in a metal container. Within the capacitor, a non-polarized electrolyte provides the electric potential for capacitance. A unique feature of the LPW153M1AN35V-W is that it contains a valve-style mechanism which enables the capacitance of the aluminum electrolyte to be regulated.

The working principle of the LPW153M1AN35V-W aluminum electrolytic capacitor is based on Faraday’s law. This law states that when the voltage applied across two metallic plates changes, the amount of charge stored in the space between the plates is directly proportional to the change in voltage. When the applied voltage increases, the current flow increases and more charge is stored. The opposite is true when the voltage decreases. The amount of charge stored is determined by the capacitance, which is the ratio between the charge and the voltage.

In addition to Faraday’s law, the working principle of the LPW153M1AN35V-W aluminum electrolytic capacitor also includes the effect of dielectric polarization. Dielectric polarization is the accumulation of a charge on the dielectric material, which further increases the capacitance of the capacitor by reducing the distance between the aluminum plates. This provides ample capacitance for applications requiring high-frequency power processing, such as power supply control and regulation.

Conclusion

To summarize, the LPW153M1AN35V-W aluminum electrolytic capacitor is a powerful tool for many power electronic applications and are widely used in a variety of industries. Its unique operating principle is based on Faraday’s law and the effect of dielectric polarization. This capacitor is suitable for a broad range of temperatures and can provide sufficient capacitance for high-frequency power processing, making it a useful component in the development of regulation and control systems.
