Fixed Inductors

Inductor, as an important electronic component, plays an important role in the fields of communication, power, consumer electronics, automotive and other fields, and contributes enormously to the development of electronic product technology. The CV201210-1R2K is a type of fixed inductor, mainly used for filtering, impedance matching, resonant circuit, oscillation circuit, energy conversion, etc. It has good performance and wide application. This article will give a comprehensive introduction to its application field and working principle.

Application Field

CV201210-1R2K fixed inductors are mainly used for filtering, impedance matching, resonant circuit, oscillation circuit, energy conversion, etc. In particular, it is widely used for filter circuits of audio amplifiers, power amplifiers, TV sets, and other digital audio equipment. In addition, they can also be used as an antenna to collect signals and prevent noise interference.In the field of power, they are commonly used in power converters, DC/DC converters, on-board chargers, and so on. When it is used as a power inductor, it can be used to achieve charged and inrush current suppression. In automotive, it is mainly used in the fields of sensor, following mechanism, purification circuit, driving circuit and so on.

Working Principle

The basic working principle of a CV201210-1R2K inductor is based on Faraday’s law of induction. It is essentially three main components—inductive energy, capacitive energy, and a resistance element—in one compact package. A typical inductor stores electrical energy as a magnetic field when electrical current passes through it.In a CV201210-1R2K inductor, current flowing through the inductor sets up a magnetic field, the magnetic field produces an opposing voltage, and the market is maintained by the inductor’s resistance. This opposing voltage opposes any change in the current flowing through the inductor, essentially limiting the flow of current in both directions.In a practical application, adjust the magnitude of resistance is very important in the design of inductor. When the voltage drop across the terminals of an inductor is large, the inductor produces a linear relationship between current and voltage; when the voltage is small, the inductor produces a non-linear relationship between current and voltage.

Conclusion

CV201210-1R2K fixed inductors are a type of inductor mainly used for filtering, impedance matching, resonant circuit, oscillation circuit, energy conversion, etc. They are widely used in the fields of communication, power, consumer electronics, automotive and other fields and their working principle is based on Faraday’s law of induction. With their compact size, simple structure, and good performance, they are becoming increasingly popular in many electronic product applications.
