Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors (AECs) are special capacitors that use an electrolyte to provide a larger capacitance value compared to other types of capacitors. AECs are formed when a thin aluminum foil is used as an anode and a wetted material such as manganese dioxide or a conducting polymer is used as a cathode. When a voltage is applied to the capacitor, the anode and the cathode become charged and an electric field is formed in the gap between them.The UHV0J821MPD1TD is an AEC specifically used in high-voltage applications. It has a maximum voltage rating of 2.5kV, with rated voltage of 1.5kV. The capacitance is 1.0μF and the leakage current is 3.2uA. It also has a temperature range between -55°C and +125°C, making it suitable for a wide array of applications.The UHV0J821MPD1TD is well-suited for use in high-voltage power supplies and medical systems, acting as a voltage stabilizer. It can also be used in power conditioning systems to reduce any drop in voltage or current and protect other components from the transients. Additionally, they can reduce electrical noise from power surges and fluctuations, as well as provide input and output filtering. The UHV0J821MPD1TD is also used in on-board power supplies and adjustable DC and AC converters for computers and vehicles.The working principle of AECs can be explained by understanding capacitors in general. A capacitor is composed of two parallel conductors (plates) separated by a dielectric material, which is the electrolyte of an AEC. When a voltage is applied across the plates, electric charges are transferred from one plate to the other. This causes an electric field to be established and a potential energy is stored in the capacitor. The capacitor then acts as a reservoir of electric energy, in contrast to a resistor, which dissipates electric power in the form of heat.The AEC works essentially the same way as any other capacitor. The electrolyte serves as the dielectric material, acting as an insulator between the anode and cathode. When the voltage is applied, ions are attracted to both plates, creating an electric field and storing energy. This energy is then slowly released, providing a continuous output of voltage to the equipment it is connected to.The UHV0J821MPD1TD AEC is a reliable, durable, and efficient capacitor suitable for a variety of applications. It is stable in high voltage conditions and can handle large currents without any significant temperature rise. The temperature range also makes it suitable for a variety of conditions, as well as for long-term use. This capacitor is an excellent choice for applications requiring high levels of voltage and current stability, and its working principle is easy to understand.
