Fixed inductors are pieces of electronic equipment commonly used in many electrical and electronic circuits. A fixed inductor is an AC element which stores energy in the form of a magnetic field when current passes through it. Generally, a fixed inductor consists of a conductor, usually a coil of wire, surrounded by a core material to enhance the formation of the magnetic field. The most common core material for a fixed inductor is iron, although materials such as ferrite are used in some applications, particularly power electronics.

The 105-122J application field and working principle of the fixed inductor are described in detail below.

Working Principle:

The basic principle behind the operation of a fixed inductor is the fact that the current which passes through it creates a magnetic field which can be stored in the core of the inductor. When the current stops, the magnetic field remains, and this creates a counter-electromotive force (EMF) which tends to oppose the change in the current. This counter-EMF is responsible for the basic characteristics of an inductor, such as impedance, inductance and inductive reactance. In addition, the current in the inductor can be used to induce an EMF in another nearby circuit via the process of induction, unless the induction is blocked via a device such as an air gap.

Application Field:

Fixed inductors are used in a wide variety of applications, from power supplies to signal conditioning. In many cases, the inductor is used to regulate the current in a circuit, for example in the output stages of an electronic power supply to reduce ripple on the output. The inductor can also be used in communication circuits to filter signals or reduce unwanted interference. In addition, inductors can be used in combination with capacitors to form tuned circuits, which can be used to select particular frequencies from a signal. Finally, they can also be used in control systems to limit the speed of motors.

The 105-122J fixed inductor is a specific type of fixed inductor used in many of the above mentioned applications. The primary features of the 105-122J are its very low inductance, high inductive reactance, and low DC resistance. These characteristics make the 105-122J particularly suitable for use in circuits which need to limit the current flow such as in power supplies, signal conditioning, and tuned circuits.

In summary, the 105-122J is a type of fixed inductor widely used in many electrical and electronic circuits. It is characterized by its low inductance, high inductive reactance, and low DC resistance, making it particularly suitable for use in applications which require current limitation.
