Fixed inductors are a type of device used in various electronic circuits or systems to store electrical energy in the form of magnetic fields. They are used to control current flow and voltage levels in electronic systems, as well as providing a level of isolation between various pieces of electronic equipment. Fixed inductors are typically constructed of a winding of wire around a ferrite or iron core. The ferrite core provides isolation between the winding and the substrate, which helps reduce resistance and increase inductance. The winding is usually made up of many turns of wire to create a high inductance.

The most common application of fixed inductors in electronic systems is in the field of power management. These devices are used to control the amount of power that flows from a power source to a load or application. In addition, they can also be used to reduce high-voltage spikes, help regulate power supply fluctuations, and protect sensitive components from excessive current levels.

Fixed inductors are also widely used in communications, speakers and audio systems, and medical devices. In these applications, they are used to reduce audio distortion, increase the clarity of sound, reduce the amount of electromagnetic interference (EMI), and increase the overall efficiency of the system.

The working principle of a fixed inductor is relatively simple. An applied voltage induces current in the winding, which creates a magnetic field. The magnetic field creates an opposing force to the voltage, which ultimately reduces the current as the voltage drops. The amount of reduction in the current is determined by the amount of inductance of the inductor.

Fixed inductors are available in a variety of sizes and types, ranging from tiny devices used in sensitive medical applications to large, industrial-grade inductors. Common sizes range from 2.0mm in diameter to as large as 32.0mm in diameter, with the largest rated at 2500–28G of inductance.

Fixed inductors are typically constructed from ferrite or iron cores, along with a variety of wire windings. For the most part, the cores and windings are grouped into two types: ferrite cores and non-magnetic cores. The ferrite core is usually a ceramic material, while the non-magnetic core can be made of a variety of metals such as aluminum, steel, bronze, or copper.

In addition to their primary purpose of controlling current flow and voltage levels, fixed inductors are also used in a variety of other roles. They are often used in power supplies to help regulate power supply fluctuations, and in battery management systems to prevent overcharging and discharging. They can also be used to reduce high-voltage spikes, provide isolation for sensitive components, reduce audio distortion, increase the clarity of sound, and reduce EMI.
