Aluminum electrolytic capacitors, typically abbreviated as AECs, are polarized electrolytic capacitors consisting of two aluminum foils separated by paper impregnated with an electrolyte. They are used in a variety of applications, including audio systems, DC power supplies, home appliances, and automotive instruments. The ULV2D120MNL1GS is a particular type of AEC designed for high-frequency switching applications. In this article, we explain the application field and working principle of this contemporary AEC.

The ULV2D120MNL1GS is a specialized aluminum electrolytic capacitor designed for use in high-frequency switching circuits. It has a rated voltage of 16 V, capacitance of 120 µF, and an ESR (Equivalent Series Resistance) of 0.45 Ω. This capacitor also has a maximum operating temperature of 105°C and a rated ripple current of 245 mA. Due to its low ESR and high ripple current, the ULV2D120MNL1GS is well-suited for applications such as voltage regulators, DC-DC converters, and LCD/LED driver circuits. Additionally, this capacitor boasts a successful use in digital home-theatre systems and computer motherboards.

From the standpoint of construction, ULV2D120MNL1GS features a non-solid electrolyte, meaning that its aluminum foils act as the anode and cathode. The capacitor is then filled with an electrolytic solution that serves to provide electrical connection between the two. As with other polarized electrolytic capacitors, the ULV2D120MNL1GS must be connected with the correct polarity; in this case, the positive terminal should be connected to the anode and the negative terminal to the cathode.

In terms of operation, the ULV2D120MNL1GS works by storing electrical charge in the form of electrostatic energy. When charge is applied, all the electrolyte in the capacitor becomes polarized, allowing charge to be stored. When the capacitor is connected with correct polarity, a process of electrolytic conduction takes place and charges are able to flow from the anode to the cathode through the electrolyte solution. As current builds up, the voltage across the capacitor at the anode will drop, and the capacitor will be fully charged once the voltage across it reaches a specified limit.

In conclusion, the ULV2D120MNL1GS is an advanced aluminum electrolytic capacitor designed for high-frequency switching applications. Its low ESR and high ripple current make it an ideal choice for voltage regulators, DC-DC converters, and LCD/LED driver circuits. The capacitor also has a rating of 16 V, capacitance of 120 µF, and a maximum operating temperature of 105°C. The capacitor’s construction consists of two aluminum foils separated by an electrolyte solution, and its working principle involves storing electrical charge in the form of electrostatic energy.
