A fixed inductor, also known as a choke, is a component used to create an inductive reactance. It is composed of either a coil of insulated wire in an air core, or a core of magnetic material, with various configurations possible (such as axial, radial, and bobbin). RL875-120M is a popular type of fixed inductor. In this article, we will discuss the applications and working principles of RL875-120M.

RL875-120M has a variety of important applications in engineering, for example in power supplies and in radio frequency (RF) circuitry. Its high current rating of 1.2A makes it suitable for a wide array of power supply requirements. Its self-induced electric fields help protect electronic components from excessive voltages and currents. In RF circuits, it helps reduce losses and improve overall transfer efficiency.

The working principle of RL875-120M can be understood on a basic level by examining the following characteristics. First, it has a self-resonance frequency, which is the frequency at which its impedance is at a minimum. This is typically at its highest inductance point. Second, its inductive reactance increases as the frequency of the signal increases. This means that it has more resistance to higher frequencies. Finally, it has a DC resistance or DCR, which is the sum of the resistance of the internal windings and the resistance of the core material. This DC resistance affects the inductance as well as the frequency response of the component.

RL875-120M is built with high-quality components, including inductance windings consisting of multiple layers of coated copper or aluminum ribbon for superior signal isolation. It is available in a wide range of sizes and inductances, so it can be used in virtually any application. Its cost-effectiveness and high reliability make it an ideal choice for many applications.

In summary, RL875-120M is a type of fixed inductor that has many practical applications in both power supplies and radio frequency (RF) circuitry. Its ability to create an inductive reactance is due to its high current rating, self-induced electric fields, and its self-resonance frequency. Additionally, its cost-effectiveness and reliable operation make it a popular choice for many engineers.
