Fixed inductors are, as their name implies, components that act as inductors with a fixed or unchanging inductance value. The CF453215-R18K is classified as a fixed inductor and has various application fields as well as a unique working principle. In this article we will discuss both the application fields and working principle of the CF453215-R18K.

Application Fields of the CF453215-R18K

The CF453215-R18K is typically used in high frequency pulse and switching circuits, particularly those with high current capacities. This type of inductor offers high current ratings and large PCB area savings thanks to its high density winding technique. Additionally, the high frequency current limit feature makes the CF453215-R18K perfect for applications with high repetitive current surge requirements such as over-voltage protection. In addition to its use in pulse and switching circuits, the CF453215-R18K can also be used in AC circuits, LCD inverters, motor drivers, and more.

Working Principle of the CF453215-R18K

The CF453215-R18K operates by utilizing the principle of electromagnetic induction. This is the result of current passing through its windings, which produces a magnetic field. By utilizing an alternating current source, the magnetic field produced by the winding will constantly fluctuate with the AC source frequency. This fluctuating field induces an electric current into the inductor, which creates a low-resistance current loop. This process produces an electric field that interacts with the magnetic field created by the current, thus helping to maintain the current in the circuit.

Due to the reaction between the electric and magnetic fields, the CF453215-R18K can work as a low pass filter, allowing low frequency signals to pass while blocking higher frequency signals. In this way, the CF453215-R18K can be used to reduce electrical noise or interference. Further, as the inductance of the CF453215-R18K is the same regardless of the frequency of the current, it is highly suitable for use in AC circuits.

The CF453215-R18K is also unique because it utilizes a high-density winding technique. By compacting the windings within the inductor, the space it occupies is drastically reduced. This technique also helps to reduce the size of the component, making it suitable for use in smaller systems where board space is at a premium.

Conclusion

In conclusion, the CF453215-R18K is a unique fixed inductor designed for use in high-frequency pulse and switching circuits. Its high-density winding technique helps to save space while also allowing it to operate as a low pass filter, making it suitable for a wide variety of applications. Additionally, its fixed inductance makes it ideal for AC circuits. Finally, its high current rating makes it suitable for applications with high repetitive current surge requirements.
