Fixed inductors are electrical components mainly used in filtering and signal processing applications. Commonly used fixed inductors are of the LEM2520T820J type. In this article, we will discuss its application field and working principle.

Basic Information

LEM2520T820J fixed inductors, also known as molded power inductors, are rugged components designed for high power applications. They are available in a variety of inductance values ranging from 2.2 uH to 4.7 uH. These inductors are ideal for high power applications due to their large size, high current capacity, and low impedance characteristics. They are also highly reliable and can be used in extreme operating conditions. They are constructed using a high permeability ferrite core for maximum efficiency.

Applications

LEM2520T820J inductors are mainly used in high power applications such as dc-to-dc converters, high current switching power supplies, and switching converters for AC-DC applications. They are also used in PFC circuits and other high power filtering applications. They are also commonly used in motor control, RF power amplifiers, and telecom equipment. Due to their small size and high current capacity, they are often used in applications where space is limited.

Working Principle

LEM2520T820J inductors work by producing a magnetic field when electric current flows through them. As the electric current flows through the inductor, a magnetic field is created that opposes any changes in the current. This phenomenon is referred to as inductance, and is the basic principle of operation for all inductors. In the case of LEM2520T820J inductors, the magnetic field is used to filter out unwanted signals and noise in the circuit, providing a cleaner signal. LEM2520T820J inductors also have a high current capacity and low resistance, making them highly efficient for power applications.

Conclusion

To summarize, LEM2520T820J fixed inductors are rugged, reliable components used in high power applications such as high current switching power supplies, dc-to-dc converters, and motor control systems. They have a high current capacity and low impedance characteristics, and are constructed using a high permeability ferrite core for maximum efficiency. These features make them an ideal choice for high power applications requiring reliable, efficient components.
