Aluminum electrolytic capacitors are polarized and have a wide range of applications in the electrical industry due to their high power and high capacitance density. The UPB2D681MRD is an aluminum electrolytic capacitor specifically designed for use in high power applications. This capacitor has a rated voltage of 420V and a capacitance of 2.81uF. Its high capacitance density makes it ideal for applications such as audio and power supply filtering.

The working principle of the UPB2D681MRD is based on the law of electrolysis. As electricity flows through an electrolytic capacitor, an electrolyte solution in which the electrolyte is dissolved in the capacitor dielectric medium is electrochemically formed, resulting in an electric double layer (EDL) at the electrode interface. This EDL is formed by ions on the dielectric medium forming an electric charge on the two electrodes. The resulting electric field between the two electrodes in the EDL attracts and holds electrical charges onto the electrodes. This results in an increased capacitance value and a higher power rating.

The UPB2D681MRD has a wide range of applications due to its high current rating, high capacitance density, and low equivalent series resistance (ESR). It is suitable for use in high power audio circuits, power supply and filtering circuits, and even in variable frequency drives. This capacitor can also be used in applications where power surges are likely to occur, as its design helps protect against current inrush and keeps the components cool even when faced with high current transients. It is also suitable for use in industrial environments where temperatures may range from -40° C to +85° C.

The UPB2D681MRD is an aluminum electrolytic capacitor that is designed for use in high power applications. Its high capacitance density and low equivalent series resistance enable it to provide high current ratings and protect against current inrush in variable frequency drive applications. Its wide temperature range makes it suitable for use in a range of industrial environments. Its versatility makes it a suitable choice for a variety of high power applications.
