In addition, its high ripple current rating makes it suitable for use in frequency converters and industrial power supplies. Furthermore, its excellent DC bias characteristics and wide capacitance range of 3.3~15000µF makes it suitable for many demanding applications.

Working Principle of ESMG351ELL1R0MF11D

Aluminum electrolytic capacitors are polarized capacitors with one positive and one negative electrode. The positive electrode is made of aluminum foil, which is etched to create a porous surface for electrolyte absorption. The electrolyte is absorbed by the aluminum and forms an insulating oxide layer, which allows the charges to accumulate on the surface and form a strong electrostatic capacitor. The negative electrode is constructed from a metal foil wound around the middle of the capacitor and connected to the aluminum foil. When an electrical signal is applied, the positive and negative charges move away from each other, creating an electric field across the oxide layer.

The electrolytic capacitors are filled with a highly corrosive liquid and have a large capacitance, making them suitable for high voltage and frequency applications. The capacitance of an aluminum electrolytic capacitor is determined by the area of the aluminum foil, the thickness of the oxide layer, and the dielectric constant of the solvent used in the electrolyte. The ripple current is also affected by the thickness of the oxide layer and the dielectric constant of the solvent. The rated voltage and temperature range of the capacitor are determined by the maximum operating voltage and temperature of the device.
