Different Types of Inductors

The different types of inductors include the following:

• Iron Core Inductor
• Coupled Inductor
• Air Core Inductor
• Iron Powder Inductor
• Variable Inductor
• Ferrite Core Inductor
• Choke

A detailed explanation for a few of them is given below:

Iron Core Inductor

Iron core inductors are made of iron and are normally used in high-power inductors, but they are limited in high-frequency capacity. They are used in places where low space inductors are required because being low space inductors, they have high inductance value when compared to air core conductors. Also, there is a significant energy loss in the process. These inductors are widely used in audio equipment.

Air Core Inductor

Air Core Inductors are hollow and are normally used in applications where the level of inductance requirement is very low. The fact that no core is used ensures there are no losses within the core and the coil is supported by the air.

These types of Inductors are effective in high-frequency settings. The core of these conductors is made up of plastic, or ceramic and so they are also known as ceramic conductors.

Iron Powder Inductor

An Iron Powder Inductor is an inductor that uses compressed iron powder in its core. This core material makes it possible to create a magnetic field around the inductor so that when an electric current runs through it, energy is stored in the form of a magnetic field.

These inductors have the ability to give relatively high values of inductance for their size and are well-suited for all types of electronic products where space and cost need consideration. These inductors are also used in power supplies, filters, and radio frequency circuits.

Ferrite Core Inductor

Ferrite Core Inductors use a rod or core made from a ferric material. The two main components of these inductors are the ferrite core and the winding. The most common material used in ferrite core inductors is ferromagnetic material which increases the formation of a magnetic field thus providing a higher inductance value.

Ferrite core inductors are further classified into two types namely soft ferrites and hard ferrites.

Choke

A choke inductor, more commonly called a “choke,” is an electrical component used chiefly for choking off or blocking alternating current (AC) while allowing direct current(DC) to pass with relatively little resistance. This sort of inductor has a high impedance to AC signals, so it effectively filters or isolates them from circuits.

Chokes are most commonly used in electronic circuits for filtering and noise suppression as well as to separate AC and DC signals.

Inductors are electrical components that create a magnetic field when an electric current is passed through them. Inductors are most commonly coil-like structures in electronic circuits that are mostly used to reduce or control electrical spikes in a circuit. There are various types of inductors including, Iron Core and Air Core Inductors. Its main functions include controlling signals and storing energy.

In this article, we will study Inductors, Types of Inductors, Functions, and Construction of Inductors, Energy stored in Inductors along with the Inductors in parallel and series, and a brief difference between inductors and capacitors.
