Fixed inductors, also known as fixed coils, are electronic components designed to store and contain electrical energy in an electromagnetic field. They are commonly used in applications such as filtering, voltage sensing, measuring capacitance, and other related tasks. The 2890R-18J is one particular type of fixed inductor. As a high-power device, it can be used for a wide range of applications.

Application

The 2890R-18J is designed for high frequency operation, which makes it ideal for a variety of applications. It is often used in power management systems, including power converters, Buck controllers, and voltage regulators. In addition, this fixed inductor can also be used for a variety of industrial applications such as motor control, lighting control, and heating control. Due to its high power rating, it is also suitable for applications in which high current is required, such as communication systems, antenna systems, and instrumentation systems.

Working Principle

The 2890R-18J inductor is made of a magnetic core and two coils. The magnetic core is made of a high permeability material, such as ferrite. The two coils are wound around the core, with one coil being the primary winding and the other being the secondary winding.

When an alternating current is applied to the primary winding, a magnetic field is generated around the core. This magnetic field interacts with the secondary winding to generate a current in it. This current, which is known as the induced current, causes a magnetic field to be created in the opposite direction, thus creating a current in the primary winding. This process is known as electromagnetic induction, and it is the principle behind all fixed inductors.

The 2890R-18J is a very powerful inductor, with a rated voltage of 18V and a maximum current of 390A. This high power rating makes it ideal for applications that require high current, such as communication systems and antenna systems.

Conclusion

The 2890R-18J is a fixed inductor designed for high frequency operation. It is often used in power management systems, industrial applications, and communication systems. It has a rated voltage of 18V and a maximum current of 390A, making it suitable for applications that require high current. The working principle behind this inductor is electromagnetic induction, and it is a very powerful device.
