Fixed Inductors

An inductor is an electrically passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. Fixed inductors, also known as coil inductors, are a type of inductor which provide a fixed inductance that does not change based on the amount of current passing through it. A common example of a fixed inductor is the 5729-RC.

Application Field

Fixed inductors such as the 5729-RC are primarily used in AC electric circuits to provide an inductor to resist changes in current as well as used to store and supply energy, with the most common types of applications being filtering, tuning, chokes, delay lines and voltage matching. They are also used in DC electric circuits for smooth switching of transistors and voltage regulation. Fixed inductors are especially suited for DC-DC converters and switched mode power supplies.

Working Principle

Fixed inductors are composed of two terminals; an ohmic loss that leads to current flow, and a non-ohmic loss that is related to the magnetic field. When AC or DC current flows through the inductor, it creates an inductive reactance. This inductive reactance resists the changes in current, leading to a lower AC or DC circulating current. The electromagnetic field that is generated in this process is stored as energy, allowing the inductor to store and release energy. In the case of the 5729-RC, this inductance is fixed, allowing for a consistent pattern of current.

The working principle behind this fixed inductor is based on Faraday\'s law of Induction. This states that whenever the magnetic field around the inductor changes, a voltage is induced. This voltage, in turn, causes a current to flow in the reverse direction, thus allowing the inductor to control the current.

By understanding the working principle of the 5729-RC fixed inductor, one can effectively utilize this component in a variety of applications. The 5729-RC fixed inductor can be utilized for filtering, chokes, tuning, delay lines, as well as a variety of other applications that require an efficient and effective way of controlling current.
