Fixed Inductors

A fixed inductor, or “choke”, is an electrical component that has electrical current travelling through it in a single direction. This electrical current creates a ‘magnetic field’ around the component, which is responsible for its inductive reactance. This can be used for numerous applications, one of which is the 2890R-30F.

2890R-30F Application Field

The 2890R-30F is a type of fixed inductor, usually used in power conversion and radio frequency applications. It has inductance values ranging from 0.0012 H to 2.2 H, and its DC resistance values range from 0.3 Ohms to 9.2 Ohms. This makes it suitable for various applications, such as voltage regulators, motor controllers, and switching power supplies.

Other applications include radio frequency interference suppression, switching filters, and instrumentation circuits. The 2890R-30F can also be used as an on-load tap-changer type of power factor correction inductor, or in the role of a reactor in battery charging systems.

2890R-30F Working Principle

The 2890R-30F works on the principle of electromagnetic induction. When a current flows through the inductor, a magnetic flux is created in the vicinity of the inductor. This magnetic flux then induces an electromotive force (EMF) on the inductor, which is proportional to the rate of change of the magnetic flux.

This EMF create a reactive current flow out the inductor, the magnitude of which is proportional to the rate of change of flux. This reactive current flow is responsible for the inductive reactance of the inductor. This inductive reactance is the primary application of the 2890R-30F.

The 2890R-30F also works as a filter. It acts as a low pass filter, allowing low frequencies to pass while blocking high frequencies. This can be used to reduce or eliminate interference due to high frequency signals.

Conclusion

The 2890R-30F is a fixed inductor that is mostly used in power conversion and radio frequency applications. It works on the principle of electromagnetic induction, where a magnetic flux is induced at the inductor due to current flow, which then creates an electromotive force. This induces reactive current flow out of the inductor, and is responsible for the inductive reactance. The 2890R-30F can also be used to filter high frequency signals.
