UPW2C331MRD

Aluminum electrolytic capacitors are a type of electrochemical capacitor. It is an energy storage device widely used in electronic circuits. It is composed of cylindrical body, connection lead wire, sealant and electrolyte. It provides typically capacitance ranging from 1uf to 100,000uf, and applied with high voltage, often higher than 1000v, but most reliable when operating at less than 50v. Some aluminum electrolytics even have capacitance of up to 450,000uf, and voltage rating up to 2,500v. These capacitors are most prevalent due to their many advantages, such as high capacitance-voltage capability, small size and low cost.

UPW2C331MRD is a type of aluminum electrolytic capacitors. It has a cylindrical body, containing a solenoid wound with electrolyzable aluminum foil and separated by a paper dielectric, immersed in an electrolyte solution. It has a wide range of application, from power supply filters, energy storage for Pulsed discharge applications, DC blocking or bypassing, to impedance filtering. Besides, these capacitors could also be used in buck, boost, and SEPIC converters, in switch mode power supplies, and other high frequency applications.

The working principle of UPW2C331MRD is that when the voltage is applied, the aluminum anode and paper dielectric act together to store energy, and form an electric field. This electric field strengthens the attraction of positive and negative charges, which results an oxide layer on the anode foil, and this helps to increase the capacitance. This oxide layer becomes thicker or thinner with changes of voltage. When the voltage is released, the oxide layer will remain, until it is completely dissipated when the capacitor is discharged.

This type of aluminum electrolytics have some characteristics, such as low ESR, high capacitance, low leekage current, and low temperature rise. It has low impedance and high temperature stability, which performs in a wide temperature range, usually from -40℃ to 125℃, or even higher. Furthermore, the UPW2C331MRD capacitors offer superior stability to temperature, voltage, and frequency changes.

In conclusion, the UPW2C331MRD is an aluminum electrolytic capacitor, with a wide range of application. It has characteristics of low ESR, high capacitance, low leak current, low temperature rise, and has a wide temperature range for reliable operation. It is suitable for use in power supplies, Pulsed discharge applications, buck, boost, and SEPIC converters, and many other high frequency applications.
