Fixed inductors, also known as chokes or coils, are components composed of a coil of wire which store energy in a magnetic field when an electric current flows through it. The SD20-102-R is a type of fixed inductor commonly used for a wide range of applications. This component is made from a copper or aluminum wire that is wound into a coil and attached to a ferrite core. The inductance value of the component is dependent on the circumference of the coil, the number of winding and the size/material of the core.

One of the most common applications of the SD20-102-R is as a power line filter. In this application, its inductive properties are used to filter out undesirable frequencies and reduce electrical noise on a power line. This is done by winding the wire around a core that is made from a material that can block or absorb certain frequencies. These inductors are also often used in radio communication systems and in audio-amplifiers.

In addition to being used as a filter, the SD20-102-R can also be used to store energy in its magnetic field. When a current is applied to the device, the coil creates a magnetic field around itself. This magnetic field can then be used to store energy which can be released when the current is removed.

The SD20-102-R also has applications in switching power supplies. It acts as a filter and is used to control the frequency of the switching signal in order to reduce electrical noise. It is also used in circuits to create a constant current source, which can be used to power electrical circuits.

The working principle of the SD20-102-R is relatively straightforward. When there is a current flowing through the wire, a magnetic field is created which stores energy. When the current is removed, the energy is released in the form of an electric field. The inductance value and other properties of the inductor can be adjusted by changing the size of the inductor or the number of windings.

The SD20-102-R is a versatile and dependable fixed inductor that can be used for a wide range of applications. It can be used as a filter, a current source, or to store energy in its magnetic field. Its working principle is relatively simple and can be adjusted to fit various applications.
