Fixed Inductors

Inductors, also known as coils or reactors, are two-terminal electronic components that add inductance to a circuit. They are commonly used in circuits where they can prosper electrical signals for a variety of applications. This article will discuss the application field and working principle of the HKQ040218NH-E fixed inductor.

Application Field

The HKQ040218NH-E fixed inductor has a wide range of applications. It is commonly used in high-speed communication, such as Ethernet transmits, mobile network base stations, and fibre optic repeaters. It is also suitable as a power inductor, filtering circuits, switch circuit, resonant circuits, and more.

Working Principle

An inductor is primarily composed of a coil of wire. When an electric current is passed through the coil, a magnetic field is generated. This magnetic field creates an opposing force to any change in the current, maintaining the status of the electric flow. This is also known as the self-inductance of the coil.

The HKQ040218NH-E fixed inductor has a core material of MnZn ferrite. The material is ferromagnetic, which increases the inductor’s magnetic permeability. This allows for a greater range of magnetic flux to be produced and therefore also lengthens its own inductance. The inductor also has a high power rating, allowing it to be used in high-power applications.

The HKQ040218NH-E fixed inductor also has a large air gap, which further increases its magnetic flux. This air gap lengthens the inductor’s effective inductance and significantly lowers its electric loss. Additionally, the inductor comes with a wide working temperature range from -40 °C to +125 °C, providing reliable performance in harsh conditions.

In conclusion, the HKQ040218NH-E fixed inductor is a reliable and versatile component, suitable for use in many different applications. Its MnZn ferrite core, large air gap, and high-temperature capabilities make it a great choice for those looking for a high-performing inductor.
