Variable Inductors

Variable inductors, also known as adjustable inductors or tunable inductors, are electronic components that are designed to vary the inductance value of a circuit. These components are used in a wide range of electronic applications, including tuning circuits, filters, and resonant circuits.

Variable inductors can be classified into several types based on their specific characteristics and applications. Some of the most common types of variable inductors include:

1. Ferrite core inductors - These inductors consist of a coil of wire wound around a ferrite core.

2. Air-core inductors - These inductors consist of a coil of wire wound around a non-magnetic core, such as a plastic or ceramic rod.

3. Sliding inductors - These inductors consist of a coil of wire wound around a non-magnetic core, which can be adjusted by sliding the core in and out of the coil to vary the inductance value.

Variable inductors are typically characterized by their inductance range, frequency response, and mechanical adjustment range. Inductance can be adjusted by changing the number of turns in the coil, the position of the magnetic core, or the distance between the coils.
