Understanding Adjustable Inductors People Should Use

An adjustable inductor is an inductor that can be adjusted to change its inductance to set a particular frequency. They are commonly found in electronic circuits because they can use a movable magnetic core to adjust the electric field, increasing or decreasing inductance by blocking the magnetic flux lines. This article describes the range of adjustable inductors available and reviews their pros of them.

What Is an Adjustable Inductor?

A typical inductive device is an adjustable inductor. Oscillating coils for semiconductor radios, line oscillating coils for TV sets, line linear coils, etc. are examples of common adjustable inductors.

Structures and characteristics of common adjustable inductors

(1) Single layer wire. Single-layer air-core coils are made by winding an insulated wire round after round. The coils can be wound on insulating bobbins such as paper tubes, plastic bobbins, or bakelite bobbins. Air core coils are often used in high-frequency circuits.

(2) Copper core coil. Copper core coils are widely used in the ultrashort wave range. The position of the copper core in the coil is used to change the inductance. This adjustment is more convenient and durable.

(3) Honeycomb coil. A honeycomb coil means that the planes of the coils being wound are not parallel to the surface of revolution, but intersect at an angle. The advantages of the honeycomb winding method are small size, small distributed capacitance, and large inductance.

How to Choosing the Right Adjustable Inductors

Adjustable inductors are a great option for any applications that require a smooth, low-impedance current path. They are often found in power supplies, audio amplifiers, and other electronic devices.  Therefore, it is important to choose a quality supplier that offers adjustable inductors.
