Fixed inductors are passive components used to store energy in the form of a magnetic field and are designed to provide electrical current capabilities within a specified range. The LEM2520TR47K is a type of fixed inductor which has a variety of uses in the electronic and radio frequency industries. This article will discuss the application field and working principle of the LEM2520TR47K.

The LEM2520TR47K is a through-hole, fixed inductor designed for use in high-frequency switching power supplies. It is constructed of ferrite to reduce core losses and features a curved back end to allow for easy mounting. The inductor has a shielded construction which reduces noise issues at high frequencies. The inductance range of the LEM2520TR47K is 4.2-13.2 µH and the current rating is 2.5A. It is designed to be used in a wide variety of applications, including: switching power supplies, power converters, inverters, and motor control systems.

The working principle of the LEM2520TR47K is based on the idea of inductance. Inductance is the ability of a component to store energy in the form of a magnetic field. When a current passes through the inductor, the magnetic field is generated, which creates an opposing force to the current. This force is referred to as inductive reactance and is represented by the letter "X". The greater the current, the higher the reactance, and the greater the opposition to the current.

The LEM2520TR47K is designed to provide accurate and stable results in a wide variety of switching power supplies. It is designed to have a low internal resistance which ensures that the output voltage remains constant, even when subjected to high-frequency switching. The construction also provides a tight tolerance, which provides more accuracy in applications. Furthermore, it is designed to have a high immunity to electromagnetic interference (EMI), ensuring that it does not interfere with other devices.

The LEM2520TR47K is a useful component for applications in the electronic and radio frequency industries. It is constructed with quality materials to reduce core losses and provide accurate and stable results. It has a wide inductance range and a current rating of 2.5A, making it suitable for various applications. The shielded construction reduces noise issues at high-frequency switching and provides good immunity to EMI. With these features, the LEM2520TR47K is an excellent choice for applications requiring high-frequency switching power supplies.
