Fixed inductors are electronic components that act as capacitors or magnets in circuits. The LEM2520T8R2J is a fixed inductor that is frequently used in power and communications applications. It is designed to withstand high levels of transient current and has a low DC resistance, making it ideal for circuits that require high-power performance.

Application Field

The LEM2520T8R2J is used in power designs for its ability to handle large currents and relatively high voltages without generating excessive heat. It can be used in power supply applications such as networking equipment, motor controllers, and audio amplification. In communications applications, the LEM2520T8R2J is commonly used for radio frequency signal generation, filtering, and antenna tuning. This device is also commonly used in high-efficiency switching power supplies and other applications that require shielded storage.

Working Principle

The working principle of the LEM2520T8R2J is based on the concept of inductance. An inductor is a type of electronic component that stores electrical energy in a magnetic field. When an electrical current passes through the inductor, the magnetic field is generated, which in turn creates a voltage within the inductor. This voltage is used to counteract the current, creating a resistance and eventually limiting the current to a desired level.

The LEM2520T8R2J has a rated inductance of 8.2mH with a current carrying rating of 4.6A. This inductor is housed in a shielded, plastic case and is designed to withstand transient currents of up to 8.5A. This allows it to be used in a variety of applications ranging from motor control, automatic data processing, and audio amplification.

In addition to its high current rating, the LEM2520T8R2J also features a low DC resistance of 0.3mOhm, which contributes to its high efficiency. This means that the device will have a lower power dissipation and generate less heat, making it desirable for high-power circuits.

The LEM2520T8R2J is a versatile fixed inductor that can be used in a wide range of applications. Its ability to withstand transient currents, its low DC resistance, and its reliable construction make it an ideal component for power and communications applications.
