Aluminum Electrolytic Capacitors are electrical components widely used in electronic devices. They are characterized as high capacitance, high reliability, low cost, and wide operating temperature range. The UPM1H390MED is one of the most common types of aluminum electrolytic capacitors being used today. It is small in size, and it has a high capacitance, making it ideal for applications such as energy storage, power management, signal filtering, and decoupling.

The structure of the UPM1H390MED aluminum electrolytic capacitor consists of a cylindrical casing with an anode (positive) and a cathode (negative). The anode is made of aluminum foil and the internal cathode is made of electrolytic paper impregnated with a dry chemical. On the outside of the capacitor is a robust protection sleeve which helps protect against electrostatic discharges and prevents it from short-circuiting.

The working principle of the UPM1H390MED is simple. When a voltage is applied across the two terminals of the capacitor, an electrical field is created within the capacitor which causes there to be a separation of charges. This charge separation causes a charge on each terminal. The net capacitance of the capacitor is determined based on the amount of charges stored on each terminal. The more charge that is stored on the terminals, the higher the capacitance.

The wide range of applications for the UPM1H390MED aluminum electrolytic capacitor include: AC/DC fan motor speed controllers, overcurrent/overvoltage detection and protection circuits, power supplies, switch mode power supplies, automotive electronics, and consumer electronics.

The UPM1H390MED aluminum electrolytic capacitor is used for energy storage, power management, signal filtering, and decoupling. With a high capacitance and small size, this capacitor is ideal for applications that require a high capacitance in a small space. Additionally, its robust protection sleeve helps protect the capacitor from electrical discharges and prevents it from short circuiting.
