Introduction

The aluminum electrolytic capacitor is one of the most important electronic components used in modern electronic circuits. It is essential for controlling the timing of electronic signals and providing smoothing of power supply ripple. There are many different types of aluminum electrolytic capacitors available, one of the most commonly used being the LGX2W181MELZ45 model. In this article we will discuss the application field and working principle of this type of capacitor.

Application Field of LGX2W181MELZ45

The LGX2W181MELZ45 model aluminum electrolytic capacitor is used in a wide range of applications such as consumer electronics, automotive, industrial and medical. The capacitor offers a capacitance range of 11.4 to 181mF as well as a rated voltage of 25V and temperature range of -40°C to +105°C. This makes it suitable for use in a wide range of applications where a high rated voltage and high temperature rating are needed.

The capacitor is also available in a range of sizes and shapes, making it easy to select the best capacitor to fit specific PCB space requirements. The capacitance is also stable over a wide temperature range, making it suitable for use in automotive and medical applications where temperature stability is important.

Working Principle of LGX2W181MELZ45

Aluminum electrolytic capacitors are made up of an anode made of aluminum foil, a cathode made of metal oxide layer and a liquid electrolyte. When an electric potential is applied, a current will flow from the anode to the cathode. As the current passes through, ions from the electrolyte are attracted to the oppositely charged surfaces, resulting in a layer of metal oxide coating the anode and creating a barrier between the metal oxide layer and the electrolyte. This barrier prevents the current from flowing between the anode and the electrolyte.

The charge stored on the capacitor is proportional to the thickness of the oxide layer and to the capacitance of the capacitor. As the voltage applied across the capacitor increases, the oxide layer acts as a dielectric material and causes the capacitance to increase. When the voltage is removed, the capacitance returns to its original value.

Aluminum electrolytic capacitors are used in a wide range of applications due to the fact that they are relatively inexpensive and require very little maintenance. They can be used in power supplies, in radio transmitters and receivers, in high-voltage test equipment and in audio and general electronic services. The long shelf life and high temperature rating of the LGX2W181MELZ45 model makes it suitable for use in a variety of applications.
