Fixed Inductors are a type of electrical component which stores energy in its core by electromagnetism. The LQW18ANR39J80D is a type of Fixed Inductor which is suitable for applications in high-frequency circuits. This type of inductor is widely used in many modern electrical and electronic applications, such as AC/DC converters, DC/DC converters, motor drives, and power management circuits.The LQW18ANR39J80D is a precise, miniature type inductor, and is designed with a self-resonant frequency of up to 10GHz. It has a low equivalent series resistance (ESR) and can be up to 0.6 ohms max. This makes it suitable for high-power applications, as it can provide greater stability under high-frequency electrical signals without too much heat generated. The construction of the LQW18ANR39J80D is composed of an insulating bobbin, powder iron core, and a copper wire wound on the core. The core of the inductor is usually protected by an external plastic case, and is usually filled with silicone rubber for improved damping of micro-vibrations.The working principle of the LQW18ANR39J80D is based on Faraday’s law of electromagnetic induction. Whenever a current passes through the copper winding of the inductor, a magnetic flux is produced around the core. This flux is perpendicular to the coil windings, and due to the self-induction effect, an opposing voltage is induced, which is proportional to the rate of current change.This opposing voltage helps to oppose the current flowing through the inductor, limiting the amount of current. By changing the number of windings and the core material, the inductance value of the inductor can be adjusted to meet the requirements of the application.The main applications of the LQW18ANR39J80D Fixed Inductor is in high-frequency switching regulators, DC/DC converters, and motor drives. They are used to provide a reliable, stable current output in amplifier circuits, and other high-frequency circuits such as those in home theatre systems, and consumer electronics.The advantages of using the LQW18ANR39J80D are its small size, low equivalent series resistance (ESR) and high self-resonant frequency. This makes it ideal for use in high-density electronic circuits, as it can provide high-power operation without generating excessive heat.To summarize, the LQW18ANR39J80D Fixed Inductor is suitable for a wide range of applications in high-frequency circuits. Its low ESR and high self-resonant frequency make it ideal for use in high-density electronic circuits, providing reliable and stable current output in amplifier and consumer electronics.
