Fixed Inductors

Category Introduction

An inductor, also known as a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. When the current changes, the magnetic field induces a voltage in the conductor. The induced voltage has a polarity which opposes the change in current that created it. The unit of inductance is the Henry (H). Mounting options include surface, through-hole, and chassis.

About Fixed Inductors

What are Fixed Inductors?

Fixed Inductors

Fixed inductors are passive electronic components that store energy in a magnetic field when electrical current flows through them. They are characterized by having a fixed inductance value, meaning their ability to store energy does not change with varying conditions. The basic operating principle of a fixed inductor involves the creation of a magnetic field around a coil of wire when current passes through it. This magnetic field opposes changes in current, making fixed inductors essential for filtering, tuning, and energy storage applications in electronic circuits.

Types of Fixed Inductors

1. Air Core Inductors

Air core inductors use air as the core material, which means they have no solid core. They are typically used in high-frequency applications due to their low inductance and minimal core losses. Their simple construction makes them ideal for RF circuits and applications where minimal distortion is crucial.

2. Iron Core Inductors

Iron core inductors have a core made of iron or ferrite, which increases the inductance value by concentrating the magnetic field. These inductors are used in applications requiring higher inductance values, such as power supplies and audio equipment, due to their ability to handle higher currents and store more energy.

3. Ferrite Core Inductors

Ferrite core inductors use a ceramic compound of iron oxide as the core material. They are highly efficient at high frequencies and are commonly used in RF applications, transformers, and EMI suppression. Their high permeability allows for compact designs with high inductance values.

How to choose Fixed Inductors?

When selecting fixed inductors, consider the following key parameters:

Inductance Value: Choose based on the required energy storage and filtering needs of your circuit.
Current Rating: Ensure the inductor can handle the maximum current without overheating.
DC Resistance (DCR): Lower DCR values are preferable for efficiency, reducing power loss.
Frequency Range: Match the inductor to the operating frequency of your application to avoid performance issues.
Core Material: Select based on the application requirements for efficiency and size constraints.

Evaluate product quality by reviewing supplier specifications, certifications, and customer reviews. Consider environmental factors such as temperature and humidity, and ensure the inductor is suitable for the intended installation environment.

Applications of Fixed Inductors
