The fixed inductor is a passive device, consisting of a coil of wire and a core, which produces a magnetic field when current is applied to it.

Fixed inductors are used in a wide variety of applications, from power supplies and audio circuits, to automotive systems and consumer electronics. In many of these applications, the inductor is used to filter out unwanted noise and interference. It can also be used in high frequency circuits to improve the load regulation and reduce ringing.

Fixed inductors come in a range of sizes, from 100 μH to 122 K μH. The higher the inductance, the greater the magnetic field that is produced. Generally, higher inductance values are used in high frequency circuits, while lower inductance values are more suitable for low frequency applications.

The operating frequency of a fixed inductor affects its performance. As the frequency increases, the inductor loses more energy due to its resistance. This is known as the skin effect, and it can reduce the inductor’s efficiency. It is important to choose an inductor with a low resistance and a good frequency response.

The operating current of the inductor affects its performance as well. At high currents, the inductor can become saturated, meaning it cannot generate a magnetic field. This can cause unwanted noise and distortion, and reduce the inductor’s efficiency. It is important to select an inductor with a high current rating.

The working principle of a fixed inductor is relatively simple. When current is applied to the inductor, a magnetic field is produced; this field induces a voltage in the inductor, according to Faraday’s law. This voltage causes a current to flow in the inductor, creating a magnetic field which opposes the original field. This opposition results in resistance to the current, which can be used to filter out unwanted noise and interference in a circuit.

Fixed inductors are used in a wide variety of applications, from audio and automotive systems, to consumer electronics and power supplies. They are particularly useful in high frequency circuits, as they can reduce the load regulation and prevent unwanted noise and interference. When choosing an inductor for a particular application, it is important to consider its rated inductance, operating frequency, and operating current.
