Fixed Inductors

At the heart of any wireless communication system is a coil, or inductor. Fixed inductors are one of the most common types of coil used in wireless applications, and the 4922R-30L is the perfect example. This article covers the application field and working principle of this particular fixed inductor.

Application Field of 4922R-30L Fixed Inductor

The 4922R-30L is a highly versatile fixed inductor built for a variety of applications. This inductor is popular in electromagnetic interference (EMI) prevention and electrostatic discharge (ESD) prevention applications, as it has an extremely high inductance. The 4922R-30L is also common in low-noise EMI/RFI noise suppression applications, where its high self-resonance frequency is crucial for lowering the level of interfering noise.

Due to its very low insertion loss and extreme stability in high-frequency environments, the 4922R-30L is also popular in high-frequency applications, such as high-frequency design (HFD) and millimeter-wave design. Finally, the 4922R-30L is suitable for use in military aviation and aerospace applications, due to its high maintenance performance (life) and its high-power saturation resistance.

Working Principle of 4922R-30L Fixed Inductor

The 4922R-30L fixed inductor works on the principle of electromagnetic induction. Specifically, when electric current passes through the 4922R-30L, a magnetic field is created. This magnetic field then induces a voltage in the inductor, producing an electrical field. This voltage then produces a current in the inductor, which is proportional to the amount of electric current passing through the inductor.

The voltage and current produced in the 4922R-30L also have the characteristics of an inductor, which are an opposition to changes in the current flow, resulting in a storage of energy. This energy is released once the current flow changes, creating an oscillation in the voltage and current.

Conclusion

The 4922R-30L fixed inductor is a highly versatile component, suitable for a wide range of applications. It works on the principle of electromagnetic induction, where an electric current produces an oscillating voltage and current in the inductor. Thanks to its high maintenance performance and low insertion loss, the 4922R-30L is a popular choice in the wireless industry.
