Inductor coils are passive electrical components that store energy as a magnetic field when current passes through them. Due to their capacity to produce inductance, which resists changes in current, they are frequently utilized in many different electronic circuits. Inductors are crucial because of this property in processes including filtering, energy storage, and impedance matching. Their fundamental functionality is based on their capacity to withstand variations in current flow while working on the principle of Faraday’s law of electromagnetic induction.
Working principle of inductors
The working principle of inductor coils is based on the relationship between current and magnetic flux. When current flows through a coil, a magnetic field is generated around it. The amount of current flowing through the coil and the number of turns in the coil directly affect how strong the magnetic field is. An electromotive force is induced in the coil as the magnetic field changes over time, generating an opposing voltage to variations in current flow.
Types of inductor coils
Inductor coils come in many different varieties, each of which is created for a particular application based on specifications including size, inductance value, core material, and frequency range. Inductor coils come in a variety of common types, such as:
Air-core inductors
Air-core inductors are devoid of a center core, and the size and number of turns in the coil are the only factors that affect their inductance. They are frequently utilized in high-frequency applications where it is crucial to have minimal losses and a high Q-factor.
Iron-core inductors
Iron is frequently used as the ferromagnetic core material in iron-core inductors, which increases inductance. These inductors are appropriate for applications needing high inductance values and low saturation currents due to the core material’s considerable increase in the magnetic field.
Ferrite-core inductors
Ferrite materials, which have a high magnetic permeability and excellent high-frequency performance, are used in ferrite-core inductors. They are frequently utilized in high-frequency circuits and power supply applications.
Toroidal inductors
Donut-shaped cores of toroidal inductors offer a closed magnetic circuit and lessened electromagnetic interference (EMI). They are frequently employed in applications where size and performance are crucial since they are small and effective.
Coupled inductors
Coupled inductors consist of two or more inductors wound on the same magnetic core. They are used for coupling signals, voltage transformation, and impedance matching.
