Fixed Inductors - RL875-390K Application Field and Working Principle

Fixed inductors, also known as chokes, are constructed using several turns of wire that is subsequently wound into a coil. They are used in electrical circuits to store energy and to prevent RF signals from entering or leaving a component. The RL875-390K is an example of a type of fixed inductor that is widely used in various industries. This paper will discuss the RL875-390K application field and working principle. The RL875-390K is a precision fixed inductor developed by TDK Corporation. It has a temperature coefficient of -2 0.2%. These inductors are usually used in applications such as high-performance switching power supply circuits, communication systems and high-end equipment such as video cams and computers. They are also used to filter out any electro magnetic interference (EMI) and radio frequency interference (RFI) that may be present in electrical circuits. The RL875-390K is constructed out of a high-quality copper coil and a magnetic core. The coil is wound with several turns of wire, while the core is made of ferrite material, which helps in increasing the inductance of the coil. As current passes through the coil, it stores electrical energy in the form of a magnetic field. The stored energy is then released when the current is removed, which helps to maintain a flow of electricity in the circuit. The RL875-390K is designed to provide precise inductance values. It operates with frequencies ranging from zero to hundreds of kilohertz, and the inductance values range from zero to tens of millihenrys. The inductance tolerance is around -2 0.2%. Furthermore, the RL875-390K can withstand high temperatures, ranging from -20 to +85 degrees Celsius.In conclusion, the RL875-390K is a precision fixed inductor that is widely used in various industry applications. It is constructed out of a high-quality copper coil and a magnetic core, which helps to increase the inductance of the coil. The inductance values range from zero to tens of millihenrys, and it is designed to withstand high temperatures. Although the RL875-390K can be used in many applications, a detailed analysis of the circuit should always be carried out in order to determine whether it is suitable for a particular project.
