Fixed inductors are vital components used in electronic circuits for many decades. In particular, the CB2518T220KV inductor stands out as one of the oldest and most robust of the fixed inductors on the market, with a proven track record of decades of reliable service. This article will explain what an inductor is, the various application fields it is used in, and its working principle.

What is a Fixed Inductor?

A fixed inductor is an electrical component used to store energy when connected to a power source and release the stored energy as soon as the connection is removed. Fixed inductors come in various shapes, sizes, values, and configurations. For example, the CB2518T220KV is a fixed inductor with two winding layers, a ferrite core, and two integral terminations.

Application Fields of CB2518T220KV

The CB2518T220KV is a popular inductor, widely used in a variety of electronic devices and circuits. Some common application fields for this inductor are RF, SMPS, lighting, and telecommunications. For instance, in telecommunications, the CB2518T220KV can be used for impedance matching, filtering, switching, and antenna coupling. It is also indispensable for designing components of base stations, switching systems, and other telecommunications systems.

In RF applications, CB2518T220KV inductors are used for impedance matching, coupling, and power supply in transmitter and receiver circuits. They are also highly effective in low-frequency switching converters and solenoid drivers, as well as in high-temperature applications such as traffic signals and LED lighting.

Working Principle of CB2518T220KV

The working principle of the CB2518T220KV is simple. When connected to an AC power source, the inductor will act as a resistor. The amount of current that it can handle depends on its winding layer and the inductance of its core. The core of this inductor is made of ferrite, which exhibits high magnetic permeability. As a result, the core creates an oscillating magnetic field when the current through the winding layers increases or decreases.

This magnetic field induces a current in the winding layers, creating an induced voltage. This voltage will oppose the initial voltage that is applied to the inductor and reduce the current in the winding layers. This is known as "inductive reactance," and it is the basis of the working principle of CB2518T220KV.

Conclusion

In conclusion, the CB2518T220KV is an indispensable device used in RF and other telecommunications applications. It is used to provide impedance matching, filtering, switching, and antenna coupling. The working principle of the CB2518T220KV is based on electromagnetic induction, wherein a magnetic field generated by its core induces a voltage in its winding layers, which oppose the predetermined electric field.
