Fixed inductors are electronic components used in electronics and electrical engineering. They are generally used in the audio and telecommunications industry, in applications such as radios, amplifiers, and data communications. In a nutshell, a fixed inductor is a conductor that has a number of loops wrapped around a core material, such as ferrite. Fixed inductors can be found in circuits from simple radios to complex communications systems.

Fixed inductors can be divided into two categories, according to their purpose: the open-loop inductors and the closed-loop inductors. Open-loop inductors are used in circuit designs as resonators or filter components. They are typically made with an insulated wire core or a ferrite core and a set of windings that wire wrap around it. Open-loop inductors are used for signal filtering because they allow signals to pass through them but restrict the amount of noise that can pass.

Closed-loop inductors are used in circuits that generate signals. They are typically made with a circular core of metal and a set of windings that wrap around it. Closed-loop inductors are used to generate signals because they are able to pass the generated signals through their windings and create a more stable output.

105-391JS application fields and working principle is a type of closed-loop inductor. The 105-391JS is a 4-wire SMT chip inductor with a nominal inductance of 0.01uH, an operating temperature range of -40 °C to +85°C, and a rated current of 3.3A. It has an effective series resistance (ESR) value of 0.05ohms, making it an ideal choice for signal generating circuits. The working principle of the 105-391JS is based on Faraday’s law of induction; when an electric current flows through a conductor, it creates a magnetic field around it, which in turn creates an electrical current in a second conductor placed in the proximity of the first one. In the case of the 105-391JS inductor, the conductor is the wire-wrapped core and the second conductor is the winding coil.

The 105-391JS is mainly used in audio and telecommunications applications, where signal generation and filtering is required. Some of the common applications of this inductor include radio transmitters and receivers, amplifiers, pulse generators, and digital-to-analog converters. It is also used in power supply circuits, where it helps reduce noise and improve the signal clarity.

In conclusion, the 105-391JS is a closed-loop inductor used in various electronic circuits. It is mainly used in applications related to signal generation and filtering. The inductor has a nominal inductance of 0.01uH and an operating temperature range of -40 °C to +85°C. Its working principle is based on Faraday’s law of induction. By restricting the amount of noise and providing a more stable output, the 105-391JS is an ideal choice for audio, telecommunications, and power supply applications.
