Inductive Components

Today, transformers, chokes and coils are vital in electronic and electrical equipment and the large variety in demand has generated an extensive range of designs and material grades.

LINTRON offer a full range of inductive components, specifically designed for every application, from miniaturized telecom components to power transformers in switched mode power supplies (SMPS).

In the menu to the left you will find a selection of different types of inductive and electromechanics components.

What is an inductive electrical component?

An inductive electrical component is a device that stores energy in a magnetic field when electrical current flows through it. The most common inductive component is the inductor, which is essentially a coil of wire. When current passes through the coil, it creates a magnetic field around it. This ability to store and release energy is the key characteristic of inductive components.

The primary property of an inductive component is inductance, which is the measure of the component's ability to oppose changes in current. Inductance is typically represented by the symbol L and is measured in Henrys (H).

Key features of inductive components include:

1. Inductance (L):
This is the ability of the component to store energy in a magnetic field. It is influenced by factors like the number of turns of wire, the material of the core (if any), and the shape and size of the coil.

2. Opposition to Change in Current:
Inductive components resist rapid changes in current. This is why inductors can smooth out current fluctuations in circuits, such as in power supplies or filters.

3. Energy Storage:
Inductors can store energy in their magnetic fields when current is flowing through them. When the current changes, the magnetic field either expands or contracts, inducing a voltage (also called back EMF) that resists this change.

4. Reactance:
In an alternating current (AC) circuit, inductive components create inductive reactance (measured in ohms), which opposes the flow of AC. This reactance increases with the frequency of the AC signal.

Inductors are used in a wide range of applications, including:

Filters:
To smooth out electrical signals by allowing certain frequencies to pass while blocking others.

Transformers:
For stepping up or stepping down voltage in AC circuits.

Chokes:
To block high-frequency signals while allowing low-frequency signals to pass.

Inductive Loads:
Such as motors and solenoids, where magnetic fields are required for their operation.

In summary, inductive components primarily store energy in the form of magnetic fields and oppose changes in electrical current, making them essential in a variety of electrical circuits and devices.
