Fixed inductors are passive components that store electrical energy in the form of a magnetic field due to the flow of electric current. The LQH32PH6R8NN0L is a high performance fixed inductor designed to meet the low loss and high frequency requirements of modern applications. This article will discuss the application fields and working principles of the LQH32PH6R8NN0L.

The most common application for the LQH32PH6R8NN0L is when used as a power supply filter in a switched-mode power supply (SMPS). due to its low on-resistance and low DCR. Its high self-resonant frequency and low reactance also make it ideal for power factor correction (PFC) and EMI filtering. The combination of these features allows it to reduce voltage ripple and minimize low-frequency signal and noise in AC-DC power supplies.

The LQH32PH6R8NN0L also has applications in the field of communication. It is often used as an impedance matching inductor for high-speed signal transmission in applications like sata/USB/Ethernet ports, mobile phones, and Wi-Fi routers. Its small size and high inductance make it very suitable for use as an RF coil in wireless communication, such as antenna tuning and filtering of base stations.

Despite its wide range of applications, the working principle of the LQH32PH6R8NN0L is fairly simple. The inductor consists of a wire coil surrounded by a core material such as ferrite or iron. When a current is passed through the coil, a magnetic field is created, inducing a voltage across the coil. This induced voltage has an opposite direction to the driving current, and is proportional to the rate at which the current changes. This opposition to current change creates what is referred to as inductive reactance. The total inductance of the device is determined by the number of turns of the coil and the permeability of the core material.

In summary, the LQH32PH6R8NN0L is a high performance fixed inductor with a wide range of applications. It is commonly used as a power supply filter in SMPSs, EMI filtering, and impedance matching for high-speed signal transmission. Its working principle is based on the creation of a magnetic field inducing a voltage across a wire coil, with the total inductance determined by the number of turns and the permeability of the core material.
