Introduction

Fixed inductors are used in electronic inertial systems and signal processing circuits to provide a stable and constant electrical current. By taking advantage of the self-inductance and magnetic properties of these components, these inductors are able to efficiently maintain the current in a closed loop, providing reliable and lasting power in a wide range of electrical applications. The 4922-16H is a type of fixed inductor, tailored specifically for use in integrated circuits and as part of other high frequency systems. This article provides an overview of this particular inductor’s application field and working principle.

Features

The 4922-16H is a shielded, leadless, surface mount fixed inductor. It is manufactured using magnetostatic technology to ensure high efficiency when used in high frequency applications. It has a low DC resistance, a wide attractive frequency range of up to 1GHz, a wide operating temperature range of 23℃ to 85℃, and very low inductance levels in the two and four H inductor lines. As a result, it is capable of providing the necessary current in a steady, efficient manner with minimal power consumption. Additionally, the shield ensures that the inductor is well shielded from electromagnetic interference.

Applications

The 4922-16H inductor is an ideal component for use in circuits and systems requiring sustained, reliable current in high frequency applications. Its low DC resistance and wide frequency range makes it suitable for a wide range of applications in the field of high frequency electronics. It can be used in DC-DC converters, multiplexers, oscillator circuits, communications systems, and various other radio frequency circuits. Due to its small size, it is also suitable for use in embedded systems, where space may be limited.

Working principle

The 4922-16H is a self-inducting device, meaning it has the ability to generate its own magnetic fields. This inductor works in a similar way to a transformer, only the winding are replaced by a ferrite core. When a voltage is applied to the inductor it starts to generate a magnetic field, which induces a secondary voltage in the core, this new voltage being equal in magnitude but opposite in direction to the initial voltage applied. This cancelling effect makes the Inductor an effective way to reduce the electrical current passing through the core, and this is what makes it so effective in delivering a stable and constant current.

Conclusion

The 4922-16H fixed inductor is an efficient and reliable way to deliver safe and constant electrical current in high frequency applications. It has a wide operating range and provides excellent electrical shielding, making it a great choice for embedded systems or complex integrated circuits. Its main strength lies in its self-inductance, which is used to reduce the level of electrical current passing through the component and thus provide a steadier current. With its range of benefits, the 4922-16H is one of the most popular fixed inductors for high frequency applications.
