<p>Fixed inductors, also known as radio coils, are electronic components that convert electrical energy into magnetic energy through an external wire loop. The LQM21PNR47MC0D is a high-voltage fixed inductor that is widely used in power supply, RF, medical, telecommunication, and industrial control applications. This article will discuss the application field and working principle of the LQM21PNR47MC0D fixed inductor.</p><h3>Applications</h3><p>The LQM21PNR47MC0D fixed inductor is designed for use in high-voltage circuits, making it ideal for many applications. It can be found in various power supplies, including AC/DC power converters and AC/AC power inverters. The inductor is also used in high-power, high-frequency applications such as RF transmission equipment, frequency multipliers, and DC resistors. In addition, it can be found in medical equipment such as X-ray machines and telephone repeaters. Finally, it can be used for motor control applications in industrial control systems.</p><h3>Working Principle</h3><p>The LQM21PNR47MC0D fixed inductor is a core-and-coil device, which means that it has two main parts: a magnetic core and a wound wire coil. The core is typically composed of high-saturation flux materials such as ferrite or powder metal. As current flows through the coil, a magnetic field is created that surrounds the core and induces a voltage on the coil. As a result, energy is transferred from the electrical energy in the current to the magnetic energy in the core.</p><p>The inductor can handle high voltages due to the high-saturation flux materials of the core, which helps to keep inductance high, even at higher voltages. It also has a low series resistance. This means that it can handle higher currents and provide more energy to the application. Additionally, the inductor has a high self-resonant frequency, which means that it can operate in high-frequency applications as well.</p><p>The LQM21PNR47MC0D fixed inductor is a reliable and versatile component that finds applications in many industries. It is used in power supplies, RF transmission, medical equipment, and industrial control systems. It works by converting electrical energy into magnetic energy using a core-and-coil design. This allows it to handle high voltages, currents, and frequencies.</p>
