Aluminum electrolytic capacitors are a type of capacitor with a very large capacitance, which is typically between 0.47uF and 4.7mF. They are commonly used in audio and communication equipment and are available in various package sizes. The UBX1K221MHL1TN is a type of aluminum electrolytic capacitor.

Application

The UBX1K221MHL1TN is a large-size radial-type capacitor, with a capacity of 22,000 microfarads, rated at 105°C and 10,000 hours. It is typically used to provide energy storage in power conversion systems, and is suitable for applications ranging from power management and microinverters to solar inverters. It is also used in motor drivers, medical equipment, lighting and audio systems.

Working principle

Aluminum electrolytic capacitors use a combination of electrolyte and aluminum foil as the dielectric material to produce a high capacitance. This capacitor is composed of two electrodes, an anode made of pure aluminum and a cathode made of electrolyte. The anode is rolled into a spiral to maximize the surface area and increase the capacitance. The aluminum anode is oxidized and an insulating layer of aluminum oxide is created. This layer of oxide provides the dielectric layer between the two electrodes.

When a potential difference is applied to a capacitor, an electric field will be created which is proportional to the potential difference, and a current will flow between the two electrodes. The current induces an electrostatic field between the two electrodes and charges the capacitor, thus storing energy. When the potential difference is removed, the stored energy will be released in the form of an electric current.

The UBX1K221MHL1TN has a leakage current of 0.2mA, a long life, and can handle high ripple voltages up to 55V. It also has a low resistance of 0.721Ω, and a high dV/dt of 8000V/µs. It offers excellent performance and reliability, making it an ideal choice for power conversion applications.
