ELXZ250ELL391MH20D

Aluminum electrolytic capacitors consist of two aluminum foils that are rolled concentrically around a paper spacer saturated in an electrolytic solution. The outer aluminum foil functions as the anode and the inner one the cathode of the capacitor. A voltage applied to the terminals causes an electrical charge to deposit ions of the electrolyte on the anode, thus creating an electric field. The ELXZ250ELL391MH20D is an aluminum electrolytic capacitor with a nominal capacitance of 250μF and a rated voltage of 400VDC.The ELXZ250ELL391MH20D has a wide range of applications. It is commonly used in power supplies, DC to DC converters, and inverters, as well as in electrolytic motor starter circuits and audio circuits. The long life and high ripple current make it ideal for applications where high performance and reliability are essential. In terms of size, the ELXZ250ELL391MH20D is relatively small compared to other electrolytic capacitors, making it convenient to use in space-constrained applications.The wide range of applications of the ELXZ250ELL391MH20D is due to its working principle. The capacitor makes use of the phenomenon of electrolysis, which allows ions to flow from one electrode to the other, creating a porous insulator that acts as a conductor. This allows current to flow through the capacitor and establish the electric field necessary for the capacitor to store energy. At the same time, the electrolyte provides a dielectric layer that prevents leakage of current.The ELXZ250ELL391MH20D can also be used in non-electrical applications such as electrostatic attraction and damping applications due to its high maximum frequency. It is also well suited for high-end audio applications such as preamps and crossover networks due to its low ESR, low leakage current, and low dielectric absorption. As it is made of aluminum, the capacitor also has a high thermal load capacity, allowing for effective cooling of the internal components.In conclusion, the ELXZ250ELL391MH20D is an aluminum electrolytic capacitor with a wide range of applications, from power supplies to audio circuits. Its working principle, which utilizes electrolysis, allows it to store energy and establish an electric field. Its small size and high thermal load capacity make it ideal for space-constrained and temperature-sensitive applications.
