Fixed inductors are components of an electrical circuit that are used to store energy in the form of a magnetic field generated by a current flowing through it. A fixed inductor is a component with a large number of coil turns and air core type construction, allowing it to store up to 3090-100J of energy and to release it in a controlled manner. The primary function of a fixed inductor is to store energy. However, it can also be used as an electromagnetic filter, for noise suppression, or as an oscillator stage to generate a signal.

The working principle of a fixed inductor is based on electromagnetic induction. When a current is applied, it creates a magnetic field that is inversely proportional to the distance from the coil axis. This magnetic field induces a voltage in the other windings due to their relative movement. This voltage is self-induced and thus the current can be reversed or "rolled back", resulting in an oscillatory response. The amount of energy stored in the magnetic field is proportional to the square of the current, making it important to ensure that the correct current is used for the application.

The applications of fixed inductors can be seen in a variety of areas, ranging from automation, telecommunications, consumer electronics, and medical devices. In automation, it is used to store energy in order to provide a reliable power supply for automation systems and to drive motor loads. In telecommunications, they serve as impedance matching components, amplifying signal strength and helping to reduce signal losses. Consumer electronics use fixed inductors for noise suppression, smoothing out power fluctuations, and protecting vulnerable components from over-current conditions or from electrical disturbances. Finally, in medical device applications, inductors are used to suppress noise in scanning devices, helping to improve image quality.

Fixed inductors provide an ideal solution for energy storage, due to their ability to store large amounts of energy in a relatively small device. The simplicity of their design and low cost also make them attractive for a range of high-volume applications. The versatile applications of the fixed inductor, and its reliable performance make it an important part of many modern electronic designs.
