Aluminum electrolytic capacitors are passive components used to store electrical energy and filter electrical signals. They are used in wide range of applications such as in audio and radio equipment, power supplies, computer equipment, and automotive applications. The capacitor type with the part number LQR2V153MSEJBN is an aluminum electrolytic capacitor. This article will discuss the application fields and working principle of the capacitor.

Applications:

The LQR2V153MSEJBN aluminum electrolytic capacitor is designed for general purpose use in power supply, audio equipment and automotive, telecommunication, computer, and industrial applications. It also has low impedance, high ripple current handling capability, and long life. These features make it suitable for applications that require low ESR, high stability and low dissipation factor.

The capacitor’s capacitance range is from 18µF to 2200µF, which is generally suitable for low frequency applications. It also has good voltage and temperature ratings, which make it suitable for a wide range of applications. It can be used in power supplies, motor control circuits, switching power supplies, and LED lighting. It can also be used in audio circuits, telecommunications, and medical equipment. Moreover, the capacitor is RoHS compliant and halogen-free, making it suitable for hazardous environments.

Working principle:

The working principle of an aluminum electrolytic capacitor is the same as any other capacitor. It consists of two metal plates separated by an insulating material, called the dielectric. When a voltage is applied to the capacitor, ions from the electrolyte move towards the opposite electrode and an electric field is created between the two electrodes. This electric field stores energy and allows the capacitor to act as a filter, allowing AC signals to pass but blocking DC signals.

The unique feature of an aluminum electrolytic capacitor is its use of an electrolyte to provide majority of the capacitance. The electrolyte is usually a liquid and serves as a source of ions which react with the oxide layer on the aluminum, increasing the capacitance. In the case of the LQR2V153MSEJBN, the electrolyte is a non-aqueous solution, making the capacitor particularly suited for high temperature and high voltage applications.

In order to ensure maximum performance, the capacitor should be mounted and soldered with proper care. When mounting, the connections should be kept as short as possible in order to reduce the equivalent series resistance. The capacitor should be handled carefully to avoid fracture due to mechanical shock. In addition, the capacitor should be used within the specified temperature range.

Conclusion:

The LQR2V153MSEJBN aluminum electrolytic capacitor has a range of applications, including audio, radio, and automotive, telecommunication, computer, and industrial applications. It has low impedance, high ripple current handling capability, and long life. Moreover, the working principle of an aluminum electrolytic capacitor makes it suitable for applications that need low ESR, high stability and low dissipation factor. Proper handling and mounting should be taken during installation in order to ensure maximum performance.
