Aluminum electrolytic capacitors are widely used in many areas due to their high operating temperature stability and wide capacitance range. One of the most popular electrolytic capacitors is UDB1H470MHM. This type of capacitor can be used for pulse applications, AC / DC filtering, and power supply smoothing.

The UDB1H470MHM has a maximum capacitance of 4700 micro farad and a working voltage of 16 volts. The operating temperature range is between -55 degrees Celsius and +105 degrees Celsius. The maximum leakage current is 3 μA at +20°C and 2 hours life expectancy is 1000 hours.

The working principle of aluminum electrolytic capacitor is based on a dielectric barrier formed at the surface of an anode, which is an aluminum foil embedded with insulating oxide film. The cathode, a liquid electrolyte, serves as the charge carriers between the two electrodes. The capacitorand the electrolyte are usually contained in a cylindrical aluminum or steel can.

In operation, a voltage is applied to the two electrodes of the capacitor, causing a current flow through the electrolyte which deposits aluminum oxide onto the Aluminum foil. This deposition of aluminum oxide gradually and reversibly increases the capacitance of the device as the oxide layer thickens. When the voltage is removed from the capacitor, the oxide layer breaks down, causing an increase in the capacitance. This process is known as capacitance drift.

In the application field, the UDB1H470MHM aluminum capacitor is frequently used for coupling, DC blocking, and power filtering. It can be used for pulse applications, AC / DC filtering, and power supply smoothing. In the case of power supplies, a 1:1000 ratio is usually used to ensure a clean power supply and reduce the ripple factor. The capacitor is also capable of handling large ripple currents, making it suitable for applications in power electronics. Additionally, the capacitor is also commonly used in many medical, automotive, and security systems.

In summary, the UDB1H470MHM aluminum electrolytic capacitor is a highly popular capacitor for a wide variety of applications. It has excellent temperature stability, wide capacitance range, and good ripple current handling capabilities. As a result, it is becoming increasingly more popular in many areas, such as medical, automotive, and security systems.
