Fixed inductors are passive electronic components used to store energy and manipulate electrical signals. One such device is the LEM2520TR39K, which is often used in a wide range of applications. This article will discuss the application field and working principle of the LEM2520TR39K.
The LEM2520TR39K is a radial leaded inductance element which has been developed for a variety of purposes. It can be used as an auxiliary inductor in DC-DC converters, an input filter in switch-mode power supplies, and an output filter in audio applications. It is also suited for suppressing high frequency interference or noise in RF circuits, and it is available in a wide variety of inductance values.
The LEM2520TR39K is built with a ferrite core and a winding made of high temperature-resistant magnet wire. The ferrite core is composed of mixed-oxide powder sintered at high temperatures, and it is designed to ensure the maximum performance while optimizing costs. The winding is then sealed with an epoxy resin, providing excellent protection against moisture and dust. The result is a component with high stability, efficiency, and low noise.
The working principle of the LEM2520TR39K is simple. When an alternating current (AC) flows through it, the core material creates a magnetic field which induces an electromotive force (EMF) according to Faraday\'s law. This force will be in opposition to the applied AC voltage, resulting in a decrease in voltage across the component. This decrease in voltage is known as inductive reactance, and is measured in ohms. The value of the inductive reactance (XL) is directly proportional to the magnitude of the inductance (L) and the frequency of the applied voltage (ω). The equation for calculating the inductive reactance is XL= 2πfL, where L is the inductance value in henries and f is the frequency of the applied voltage in hertz.
In addition, the self-resonant frequency (SRF) of the component can also be determined. This is the frequency at which the inductance and capacitance are equal, resulting in minimum impedance. The SRF is an important characteristic for the design of RF circuits, as it determines the peak frequency of a filter, transformer, or oscillator circuit. For the LEM2520TR39K, the SRF is approximately 20 kHz.
In conclusion, the LEM2520TR39K fixed inductor is particularly well-suited for a wide variety of applications, from DC-DC converters and switch-mode power supplies, to RF circuits. It is built with a ferrite core, winding made of high temperature-resistant magnet wire, and a sealed epoxy resin for protection. The working principle relies on Faraday\'s law, with inductive reactance being measured in ohms, and the self-resonant frequency is around 20 kHz.
