2890-42K Fixed Inductors: Application Field and Working Principle

The 2890-42K fixed inductors are used for a variety of applications in industries including medical, industrial, high-speed digital, consumer electronics, and aerospace. These inductors are designed to create the best performance as well as low cost and long life.

Application Field:

The 2890-42K fixed inductors are designed for a wide range of applications in industrial, medical, consumer electronics, and aerospace. They are highly effective in a variety of applications such as decoupling, voltage regulators, power supply line filtering, signal line filtering, circuit termination, circuit protection, transient suppression, and AC line filtering. In addition, they can also be used for high-frequency switching applications, inductor-transistor oscillators, and line transformers for power factor correction.

Working Principle:

The 2890-42K fixed inductors are based on the basic physical principle of induction. When a current is applied to a wire loop, a magnetic field is generated around the wire. This field will produce a force opposed to the source current, known as an inductive reactance. The amount of this reactance is directly related to the size and number of turns in the loop, as well as the permeability of the material used for winding the coil. The number of turns in the coil determines the amount of inductance in the device. The 2890-42K fixed inductors are designed to create the desired inductance for a given application. They are winded with high-quality copper wire to give an optimal amount of inductance. In addition, the type of wire insulation used affects the inductance of the device as well as the operation temperature range.The inductor also works with the natural frequency of the system. As the frequency of the system changes, the inductance of the 2890-42K fixed inductors also changes. This is due to the change in the magnetic field that is generated by the current flow. As the frequency increases, more flux is generated, thus increasing the inductance. As the frequency decreases, the flux reduces and the inductance decreases.

Conclusion:

The 2890-42K fixed inductors are designed for a variety of applications in industrial, medical, consumer electronics, and aerospace. Their working principle is based on the physical principle of induction, where an electric current passes through a wire loop to produce a magnetic field. The amount of inductance of the device is determined by the number of turns in the coil and the type of wire insulation used. The inductor also works with the frequency of the system, where the frequency affects the flux generated and thus, the inductance of the device.
