Aluminum electrolytic capacitors are a type of capacitor that offers high capacitance values in a relatively small package size. They are widely used in a variety of electronic circuits and applications, from consumer electronics to large scale industrial installations. The UBX2A221MHL is a popular aluminum electrolytic capacitor, based upon low-impedance conductive polymer technology. This article will explore the application fields and the working principle of the UBX2A221MHL capacitor.

The UBX2A221MHL is often used in high-current and high-power applications, such as in power supplies, resonant circuits, or electric motors. The capacitor has an insulation material between the anode and cathode, allowing it to store large amounts of electric energy and then release it as needed. The main purpose of using the capacitor is to decrease the total current flowing through the circuit while maintaining its voltage. This is accomplished by storing the excess current in the capacitor and releasing it back into the circuit when the voltage drops. As such, the capacitor helps to minimize the amount of current flowing through the various components of the circuit, resulting in higher efficiency.

In terms of the working principle, when a voltage is applied to the terminals of the capacitor, an electric field is produced between the anode and the cathode. This electric field will induce a charge, causing the anode and cathode to become slightly attracted to each other. This attraction can be increased or decreased depending on the applied voltage. As the electric field builds, the capacitance also increases, resulting in a lower impedance across the terminals, which can help reduce the total current flowing through the circuit.

In terms of its physical characteristics, the UBX2A221MHL has a size of 40.0 x 25.2 x 8.3mm, a max liquid temperature of 85°C, and a voltage range of 6-50v. It also has a low ESR value of 0.0045 Ohms and is RoHS-compliant. The capacitor can also handle high ripple currents with a peak value of 140A and a continuous value of 112A. The capacitor also has a low self-inductance value of 7.1uH.

The UBX2A221MHL aluminum electrolytic capacitor is ideal for a variety of applications, from high-current power supplies and resonant circuits to electric motors and more. With a low ESR and a low self-inductance value, the capacitor offers great performance and efficiency for a wide range of applications. Furthermore, it has a rugged design that can withstand high temperatures and high ripple current loads.
