Fixed Inductors

Inductors, also known as coils, chokes or reactors, are devices that are used to establish and maintain a magnetic field. Fixed inductors, sometimes called wound inductors, are primarily composed of a coil or coils of wire that are formed into a geometric shape. Fixed inductors are designed to occupy only a small amount of space and are typically made from metals such as copper or iron. The 2890R-38F is a type of fixed inductor.

2890R-38F Application Field

The 2890R-38F is an adjustable fixed inductor designed for use in a variety of consumer and industrial applications. It is used in radio frequency and audio frequencies in the 3 kHz to 400kHz range. The inductor can also be used in transformers, electrical circuits, power supplies, and other adjustable inductors. The device has a selfless design that can easily be adjusted to meet different requirements.

Working Principle

The 2890R-38F utilizes the principle of inductance to create a magnetic field and adjust the current through the inductor. Inductors are able to resist the change in current, storing electrical energy when the current\'s direction is altered. The inductance is determined by the properties of the coil, such as its size, shape, and number of windings. The inductance can be adjusted by changing the number of windings or the size of the coils.

The 2890R-38F consists of an adjustable coil inside an insulated housing. It can be adjusted by turning the dials on the housing, altering the number of windings and the coil dimensions. The inductance is measured by passing a current through the coil and measuring the voltage drop as a result. The 2890R-38F operates well in temperatures ranging from -55C to +125C.

Conclusion

The 2890R-38F adjustable fixed inductor provides a simple and cost-effective solution for consumer and industrial applications. It can easily be adjusted to meet a variety of requirements, and is able to withstand higher temperatures than traditional fixed inductors. The inductance can be adjusted by changing the number of windings or the size of the coils. With its versatility and adjustable features, the 2890R-38F is a great choice for a wide range of applications.
