Fixed Inductors

Fixed inductors are electronic components used to introduce inductance into a circuit. They are widely used in various applications, from radio frequency (RF) to power electronics. The 4554R-4R7M is a popular fixed inductor that has become a popular choice for many of the world’s top electronics designers. This article will discuss the application field and working principle of the 4554R-4R7M.

Application Field

The 4554R-4R7M fixed inductor is used for RF and power applications. It is specifically designed for low frequency switching, small signal filtering, and power management in high-frequency circuits such as those found in mobile phones, entertainment systems, and automotive electronics. This inductor has a high self-resonance frequency, excellent stability, high current handling capacity, and low DC resistance. This makes it well-suited for high-current as well as low-power applications.

Working Principle

Fixed inductors work by introducing a magnetic field into an electronic circuit. This magnetic field is created by the movement of electrons through the inductor’s winding. The magnetic field induces a voltage that can be tapped at the output. The magnitude of the output voltage is determined by the inductance of the device. The 4554R-4R7M inductor utilizes a folded ferrite core design to provide the necessary inductance. The folded core design increases the inductor’s inductance while keeping its size compact. The 4554R-4R7M has a maximum operating frequency of up to 3MHz, making it ideal for a variety of applications.

Conclusion

The 4554R-4R7M fixed inductor is an excellent choice for a wide range of applications. Its folded core design improves its magnetic characteristics while keeping its size and power requirements to a minimum. Furthermore, its high self-resonance frequency and low DC resistance make it ideal for high-frequency applications.
