Introduction

Aluminum electrolytic capacitors are widely used in electronics products due to their relatively low cost and impressive component density.These components can be found in a variety of consumer products - from toasters to smartphones and beyond. In this article, we\'ll talk about the application field and working principle of a specific type of aluminum electrolytic capacitor: the 250VXH390MEFCSN22X35.

Application Field

The 250VXH390MEFCSN22X35 aluminum electrolytic capacitor is designed to supply high ripple current and large energy densities in a relatively small and lightweight form factor. This type of capacitor is typically used in audio and video equipment, air conditioners, precision electronics, medical equipment, automotive applications, and other industrial electronic equipment. The capacitor is able to withstand high temperatures and offers excellent electrical performance in the range of -40 to +105 Celsius.

Working Principle

Aluminum electrolytic capacitors are based on the principle of electrolysis where a thin aluminum foil is anodized with the aid of an electrolyte to form a porous oxide layer that serves as the dielectric. This layer provides an insulation layer between the two aluminium foils. When an appropriate voltage is applied across the two electrodes of the capacitor, an electric field is generated that brings the charges of opposite polarity on the positive and negative foils into contact. This creates a capacitive effect that is used in a variety of devices. The Capacity of the 250VXH390MEFCSN22X35 aluminum electrolytic capacitor is determined by its size and its dielectric layer thickness. It has a rated voltage of 250V and a maximum rating of 2500 volts. This capacitor is constructed with a low impedance polymer cathode foil and provides high ripple and surge current ratings. The capacitor also features a high capacitance value to voltage ratio.

Conclusion

The 250VXH390MEFCSN22X35 aluminum electrolytic capacitor is an ideal choice for a range of applications due to its small size and impressive ripple current and energy densities. This type of capacitor is used in audio and video equipment, air conditioners, medical equipment, automotive applications, and other industrial electronic equipment. As its name suggests, it is based on the principle of electrolysis which enables it to offer excellent electrical performance in the range of -40 to +105 Celsius.
