Aluminum electrolytic capacitors are the most widely used capacitors in the field of electronic components. UHD1E821MPD1TD is one type of aluminum electrolytic capacitors. It has a wide range of application fields and working principles.

Application Field

UHD1E821MPD1TD is suitable for all kinds of high frequency and high current DC circuits. It is mainly used in power supply circuits, filter circuits, high frequency circuits and ripple suppression circuits of power electronic products. It can also be used in other fields such as security, radio and television, household appliances, electronic computers, power supplies and communication engineering.

Working Principle

UHD1E821MPD1TD working principle is based on the principle of electrolysis. It is composed of two aluminum foil which are anode and cathode. The insulating paper is sandwiched between them and immersed in the electrolyte. The electrolyte is composed of NH4Cl and KOH. When working, as the current flows through it, oxygen ions are generated and deposited on the anode. When a sufficiently high voltage is applied, an oxide film is formed on the surface of the anode, forming an electric double layer capacitor, which has the effect of storing electric energy. Due to the difference between the oxygen ions generated on the two sides, the capacitor has a positive and negative polarization. In addition, it also has the characteristics of high volumetric efficiency, low leakage current and large capacitance.

In summary, UHD1E821MPD1TD is a kind of aluminum electrolytic capacitor, which has a wide range of application fields and working principles. Its working principle mainly uses the principle of electrolysis. It has the characteristics of high volumetric efficiency, low leakage current and large capacitance. It can be used in power supply circuits, filter circuits, high frequency circuits and ripple suppression circuits of power electronic products.
