Fixed inductors come in various shapes and sizes, but they all function similarly. These inductors, represented by the symbol B82111B0000C020, have a few common characteristics that distinguish them from other inductors. This article will discuss the application field and working principles of fixed inductors, specifically, the B82111B0000C020 model.

Fixed inductors are found in various electronic devices, from TVs and radios to computers and appliances. They are used to control the flow of electricity, prevent overloads, and store energy for use in the system. The B82111B0000C020 model is primarily used in power supplies, allowing a certain voltage or amperage to be maintained across a circuit. They are also used in radio frequency circuits, regulating the signal to reduce interference and noise.

The main components of the B82111B0000C020 inductor are the core coil and substrate. The core coil is made up of several insulated coils, wound in succession. This causes the resistance of the coil to increase until it reaches the maximum rated value. The substrate is usually composed of a ceramic or ferrite material. It acts as a shield, preventing the core coil from radiating its energy in all directions and increasing the inductance of the system.

Upon the application of a voltage, a current will flow through the coil and the result will be a magnetic field created by the alternating current. This field causes a force to oppose the current flow, resulting in inductive reactance. The inductive reactance is inversely proportional to the frequency. Higher frequencies will reduce the inductive reactance, while lower frequencies will increase it. Higher frequencies also reduce the power dissipated by the inductor.

The fixed inductor can be configured in various ways, depending on the application and its requirements. The core coil can be wound in either a single or a double layer configuration. Single layer inductors have a higher inductance than double layer inductors, but have poorer efficiency and power dissipation. The substrate can be configured in a variety of ways, depending on the size and shape of the application. The size and shape of the substrate also affects the inductance value, as larger and heavier substrates will offer higher resistance.

The B82111B0000C020 inductor is a type of fixed inductor used in power supplies and radio frequency circuits. It consists of a core coil and substrate, both of which are configured in different ways depending on the application. It is characterized by its inductive reactance, which is inversely proportional to the frequency. The core coil can be wound in either a single or a double layer configuration, while the substrate can be configured in a variety of ways based on the size and shape of the application.
