Inductor symbols

About these inductor symbols

The symbols of the inductor play a significant role in electronics and electrical circuit diagrams. All of the above symbols represent different types of inductors. These are passive devices used in circuits to store energy in a magnetic field.

These symbols help engineers and techs understand an inductor's performance in a circuit. This aids in designing, analyzing, or solving problems with inductors.

Knowledge of inductor symbols is essential for anyone concerned with electrical schematics. Every symbol gives particular info about the kind of inductor, the type of core, and any possible modification.

For example, there can be symbols for common inductors, those with an iron core, or variable inductors. It is important to know these symbols so that one can be able to understand and design circuits well.

Inductors are critical in devices like transformers, filters, and oscillators. They regulate the flow of electric current and energy. Symbols vary to indicate inductors with certain features, like variable inductance or shielding. This helps users select suitable parts for a circuit. To this end, this article isolates each symbol to facilitate the explanation of their use and purpose.

Once you get a better understanding of the inductor symbols, you will be able to map them to real-world use. For instance, iron core inductors are best for power supplies. The shielded inductors minimize electromagnetic interference in circuits. You can improve your performance by understanding these symbols. They can help you install circuits that will have low failure rates.

This guide also focuses on variable inductors which are used for tuning circuits. Symbols for variable inductors show how to adjust the designs. This can achieve various operating parameters in RF circuits. This simplifies the designers' job when it comes to meeting certain requirements in a system.

Let's take a look at a few important inductor symbols:

Generic inductor

This symbol is the generic inductor symbol of the basic inductor used to store energy in the magnetic field. It is widely used in different circuits of electronics to regulate the current.

Iron core inductor

The symbol drawn in the figure is an inductor with an iron core. This increases the inductor's magnetic field. This type is most suitable for high-power applications since it can easily cope with stronger magnetic fields.

Analogue delay line

The analog delay line symbol stands for a circuit that delays an analog signal by a specified time interval. It is employed in signal processing for phase shifting or in synchronizing signals.

Variable ferrite core inductor

The variable ferrite core inductor symbol means inductor with a ferrite core but the value can vary. This type varies in inductance; thus it is employed in tuning circuits.

Continuous variation inductor

This symbol depicts an inductor that has its inductance setting continually adjustable. It is used with applications where there is a need to control the amounts of inductance adjustment in a range.

Stepwise variable inductor

The symbol with the stepwise variable is an inductor. Its inductance varies in steps. It is well suited for use where adjustments are made as set rather than on a sliding scale.

Inductance with power points

This symbol indicates an inductor and the places where it connects to a power source. It is mainly applied in those circuits where inductance and power connections require accurate interconnection.

Shielded inductor

The symbol that looks like a standard inductor but is surrounded by a rectangular shield is the symbol for a shielded inductor. This type is commonly used in circuits that require low levels of 'outside' magnetic interference.

Bifilar inductor

The bifilar inductor symbol is found where there are two parallel windings for the inductor to improve its inductance characteristics. It is widely applied in transformers and circuits with high mutual coupling.

Variometer

The variometer symbol is an inductor that uses a variable inductance that is produced by the movement of coils. This inductor is usually employed in radio-frequency circuits to adjust small frequencies.
