Fixed Inductors are a type of electronic component that generates a controlled amount of inductance. The 4379-823JS is an example of a fixed inductor, specifically a radial leaded, surface mount device that operates from a 5 VDC supply. This part has an inductance of 1mH with a ±20% tolerance.

Fixed inductors are commonly used in a variety of applications, including power supplies, switching circuits, and wave-shaping circuits. They are also used in high-frequency applications such as radio and television, where the inductance of the component helps to filter out unwanted frequencies.

The working principle of a fixed inductor is based on the physical observable fact that the current flowing through a coil produces a magnetic field. The inductance of the fixed inductor is directly proportional to the number of turns in the coil and the area enclosed by the coil.

In practice, the inductance of a fixed inductor is changed by varying the number of turns in the coil. This can be done by either winding more turns of wire around the coil or by removing some of the turns already present. The inductance is also affected by changing the area enclosed by the coil, such as by increasing or decreasing the diameter of the coil.

When a voltage is applied to the coil, a current starts to flow through the coil. This produces a magnetic field around the coil, and this in turn induces a voltage across the coil, which is directly proportional to the rate of change of the current. This induced voltage tries to oppose the change in current, and this effect is known as inductance.

Fixed inductors are also available in various configurations, such as axial leaded devices, air-core, ferrite-core, and toroidal core inductors. In addition to these varieties, there are also various power levels available for different applications.

Overall, the 4379-823JS is an example of a fixed inductor. It has an inductance rating of 1mH with a ±20% tolerance and a 5 VDC operating voltage. This type of component is used in various applications, with the primary function being to filter out unwanted frequencies in high-frequency applications. The working principle is based on the production of a magnetic field when a voltage is applied to the coil, which induces a voltage across the coil in proportion to the rate of change of the current.
