Fixed inductors, more commonly known as coils, are components primarily used to store electrical energy and control the current flow in an electrical circuit. They are passive electronic components that have a stationary magnetic field and are designed to produce stable and reliable electrical current when subjected to an external magnetic field or alternating current. The LQH3NPN100NJ0L is a fixed inductor manufactured by TDK Corporation and is a popular choice among engineers because of its advanced features and functionality. This article will provide an overview of the application field and working principle of the LQH3NPN100NJ0L.

The LQH3NPN100NJ0L is a surface-mounted fixed inductor designed for use in high-frequency applications such as switch-mode power supplies, DC/DC converters, and low-noise amplifiers. This inductor boasts a wide surface-mount package size of 9.7 mm x 5.2 mm x 4.3 mm, making it an ideal choice for close-quarter circuit board layouts. In addition, this inductor also features a low-resistance DC resistance of 0.015 Ω, making it extremely efficient in dissipating power.

The wide range of applications for the LQH3NPN100NJ0L fixed inductor include telecommunications, automotive, industrial, and consumer electronics. The inductor is also suitable for use in radio frequency and telecommunications equipment, as well as circuit designs for computers and peripherals. This is due to the LQH3NPN100NJ0L’s low profile and long inductance range of 1.0 µH to 10 µH that allows for optimal design flexibility. Furthermore, the inductor’s low-resistance DC resistance makes it highly efficient in dissipating power.

The working principle of the LQH3NPN100NJ0Lfixed inductor is based on the Faraday’s law of induction. This law states that an electric current produces a distortion in a surrounding magnetic field. This distortion will induce an electric current in an adjacent conductor, allowing an electric circuit to be completed. In the case of a fixed inductor, the component itself creates an alternating magnetic field, and this field will induce an electric current in an adjacent conductor when it interacts with an external voltage. The alternating current created by the external voltage will then interact with the magnetic field produced by the fixed inductor, creating an electric current and resulting in circuit completion.

In conclusion, the LQH3NPN100NJ0L fixed inductor by TDK Corporation is an efficient and reliable component for high frequency applications such as switch-mode power supplies, DC/DC converters, and low-noise amplifiers. The inductor’s wide surface-mount package, low-resistance DC resistance and long inductance range makes it an ideal choice for circuit board layouts requiring close-quarter designs and optimal design flexibility. Moreover, the inductor’s working principle is based on Faraday’s law of induction, which states that an electric current produces a distortion in a surrounding magnetic field, inducing electric current in a nearby conductor and resulting electrical circuit completion.
