Aluminum electrolytic capacitors contain an anode made of aluminum foil, an electrolyte (either liquid or a gel substance) and two current-conducting charge plates in a semi-liquid form to produce an electric field. This type of capacitor generally has a high capacitance per unit volume and is used in high-current, high-frequency, high-temperature, and other high-power applications. Additionally, aluminum electrolytic capacitors are typically polarized and require a positive terminal voltage for the anode.

UKL2A471KHD is a type of aluminum electrolytic capacitor. It has the feature of long life and high reliability, making it a preferred choice for applications in high voltage, power conversion, automotive, and industrial applications. It has relatively low leakage current and meets the stringent requirements of power electronic equipment that need long operational life.

The UKL2A471KHD is a standard electrolytic capacitor with a maximum rated voltage of 175 Volts and a capacitance range from 120 to 220 μF.

The working principle of a UKL2A471KHD aluminum electrolytic capacitor is that of an electrochemical cell. When electric current is applied across its terminals, the aluminum foil anode dissolves due to the reaction with the electrolyte and the charge plates become polarized. This polarization causes the positive ions to accumulate and the negative ions to migrate towards the cathode, creating a potential energy that is then released when the capacitor is discharged.

The UKL2A471KHD is used extensively in power supplies, measuring instruments, electronic ballasts, industrial automation, solenoid valves, and other power electronics applications where long life and high reliability are critical factors. It is also useful in power factor correction of power supplies due to its large capacitance.

In addition, it is also often used in UPS systems and resonators for suppression of switching noises emitted from control circuits, as its features match the design requirements of each application. Furthermore, its small size and long life make it a preferred choice for portable equipment.

The UKL2A471KHD is also a preferred choice for automotive and IGBT systems due to its low ESR and excellent heat resistance. Due to its high capacitance, it can be used to reduce the ripple current in the system and prolong the reliability of the drive system. Finally, its long operational life also leads to reduced maintenance costs for automated systems.

In conclusion, the UKL2A471KHD aluminum electrolytic capacitor is a reliable and durable capacitor, used in many high-voltage, high-power applications. due to its high capacitance and excellent heat resistance, it can be used for power factor correction in power supplies, suppression of switching noises, and reduction of ripple current in automotive and IGBT systems for reliable and efficient operation.
