Fixed Inductors are essential components for controlling the flow of electrical current, particularly in alternating current (AC) circuits. As the name implies, they are also widely used to provide inductance, a property that provides an opposition to the flow of electrical current. This type of component is composed of a coil or winding of wire arranged to create a magnetic field, a process that determines the inductance level.

The most common form of this type of component is the air-core inductor, which provides only very modest inductance concentrations, yet they are still highly valued because of their simplicity. They do not suffer from the same kind of reliability issues as inductors composed of windings over ferromagnetic cores.

In terms of more substantial inductance levels, the use of a ferromagnetic core will usually be required. Such devices are classified into various types, depending on the type of core used and the size of the magnetic field created by the winding of the wire. One example of this type of device is the 108-153K family of fixed inductors.

The 108-153K family of fixed inductors offers a range of inductance values from 0.108 to 1.53kµH. It also comprises several different types, each of which utilises a diverse range of materials, depending on their application requirements. The family includes, for instance, coils made from ferrite core and shielded inductors, as well as units that are constructed using various metallised films.

The core material used will depend largely on the specific frequency range that the inductor will be required to operate within, as well as the amount of current that it needs to handle. Ferrite cores have a high permeability ratio, enabling them to provide exceptionally high inductance levels. This means they are particularly well-suited for applications such as RF filters and audio circuitry.

The 108-153K devices also provide a number of other useful features. These range from optional solder tab terminations for higher current device packages to axial leaded magnetically shielded components that provide exceptional noise suppression. Many of the more advanced versions also offer a range of current rating options, with some devices providing high current ratings and others having capabilities up to low voltage sparks.

As with any such component, the workings of the 108-153K family of fixed inductors can be understood by examining their basic working principles, such as the Faraday principle. When an AC current passes through a loop of wire, a magnetic flux is generated and the associated magnetic field causes an electric current to flow around the loop. This phenomenon is referred to as “induced current”.

As the current passes through the loop, it creates a directional changing magnetic field, which in turn forces the electric field to take the same direction as the changing magnetic field. This exerts a force on the electron charges surrounding the loop, in effect, producing an increase in inductance.

The Faraday principle can be used to explain the overall functionality of the 108-153K family of fixed inductors. The ferrite core components have a higher permeability than the air-core types and this serves to increase the inductance level. The various types of metallised films used in the construction of the devices also contribute towards the over inductance level, as the materials provided increased current paths for the magnetic field lines to flow around.

In summary, the 108-153K family of fixed inductors is a versatile range of components providing accurate and reliable inductance capabilities in various conditions and environments. They are capable of handling a range of frequencies and current levels and they also offer various termination options. It is highly advisable to consult an expert in this field when making a selection, to ensure the desired performance from the inductor is achieved and fully realised.
