Introduction

Fixed inductors are an essential part of electrical circuits and the LEM2520TR18J is a type of fixed inductor. Fixed inductors are typically used to store energy in the form of magnetic energy and convert it to electrical energy. They also help to provide power to sensitive electronic components in a circuit. The LEM2520TR18J is a type of low profile, surface mount fixed inductor with a low resistance value and high saturation current.

Application Field

The LEM2520TR18J can be used in a variety of applications. Thanks to its low profile design, it is suitable for use in consumer electronics, automotive, aerospace, and other applications. It is ideal for use in high frequency circuits, such as voltage regulators, switching power supplies, and audio amplifiers.

Characteristics

The LEM2520TR18J has several characteristics that make it an ideal choice for many circuits. It has a low resistance value of 0.25 ohms, a high frequency current capability of 20 Amps, and a saturation current of 200 Amps. It has an inductance of 0.25uH, a Q-factor of 8 mH, and a temperature coefficient of 100 PPM/C. Additionally, the LEM2520TR18J is a surface mount component, making it easier to install and connect to other components in a circuit.

Working Principle

The LEM2520TR18J works by using a process called mutual inductance. Mutual inductance occurs when two coils are placed near each other, and electric current flows in one coil causes an electric current to be induced in the other coil. This process essentially allows energy to be transferred from one coil to the other.In the case of the LEM2520TR18J, the electric current flowing in the primary coil induces an electric current in the secondary coil, which is the inductor. The energy transfer from the primary coil to the inductor causes the inductor to create its own magnetic field, storing the energy in the form of magnetic energy. When the current flowing in the primary coil is removed, the energy stored in the inductor’s magnetic field is released, creating an electric current in the secondary coil. This electric current is then used to power the other components in the circuit.

Conclusion

The LEM2520TR18J is a type of fixed inductor and is capable of storing energy in the form of magnetic energy and then releasing it as an electric current. It has a low resistance value and high saturation current, making it ideal for use in high frequency circuits such as voltage regulators, switching power supplies, and audio amplifiers. Additionally, the LEM2520TR18J is a surface mount component, making it easier to install and connect to other components in a circuit. Overall, the LEM2520TR18J is an ideal choice for many applications and is well-suited for consumer electronics, automotive, aerospace, and other applications.
