Fixed Inductors

A fixed inductor is an electronic device that consists of conductors that form a circuit through a magnetic core which is capable of storing energy as electrical potential in a magnetic field. The 2890R-42K is a type of fixed inductor that is designed to have a wide range of applications. The main features of this type of inductor are its low-resistance structure and its wide-ranging frequency tolerances.

Applications

The 2890R-42K fixed inductor can be used in a variety of applications that require high-frequency and low-resistance performance. It can be used for high-speed serial communications, switching power supplies, and SMPS applications. In addition, it can be used in motor control, switch mode regulators, and line filter circuitry. This type of inductor is also well-suited for AC circuits that require high-frequency operation such as RF and audio circuits.

Working Principle

The 2890R-42K inductor works by using the magnetic core to store electrical potential in a magnetic field. This electrical potential is then released gradually over a certain amount of time while the current flows through the inductor. The time it takes for this electrical potential to be released is determined by the inductance, which is the basic measure of an inductor\'s opposition to changes in the current. Since the inductor is composed of many turns of wire, it is able to produce a large field when the current flows through it.

When the current is applied across the inductor, the field around the wire produces opposing forces which oppose the flow of current. This causes the current to slow down and decrease in intensity as it travels through the inductor. This creates a voltage drop, and over time, the voltage starts to increase again as the magnetic field around the inductor dissipates. This is how the inductor works, and this is why it is so useful in such a wide range of applications.
