Introduction

Fixed inductors, sometimes called nonadjustable inductors, are electrical components consisting of coils of insulated wire wrapped around a core. The core material can be ferrite, air, or powdered iron. The purpose of a fixed inductor is to store energy in the form of an electromagnetic field created by the current through the conductor. An inductor acts as a choke when impedance is high enough, and it works to create a low-frequency LC filter with capacitors. LAN02TA181J is an example of a fixed inductor, and this article will discuss its application field and working principle.

Application Field

The LAN02TA181J is suitable for a large variety of printed circuit boards. It has low DC resistance, high-frequency characteristics, and can withstand temperatures of up to 125°C. Its compact size makes it ideal for consumer electronics such as TVs, radios, DVD players, and audio systems. It is also used in automobile audio, automotive power systems, high-end audio equipment, and professional audio applications, such as mixing boards. Additionally, it can be used in the aerospace industry and on military projects.

Working Principle

The LAN02TA181J uses inductance to create a low-pass filter that blocks any noise, spikes, or high-frequency interference from passing through. The component works by transferring energy from the core to the surrounding air or ferrite core, creating a magnetic field. This magnetic field aligns with the current flowing through the inductor, and opposes any changes in the current. The inductance is determined by the number of turns of the wire and the type of core material. When connected to other components, such as capacitors, the component creates a low-frequency LC filter. This filter acts to limit the amplitude of vibrations, in order to reduce damage to the components and prevent noise from being generated.

Conclusion

The LAN02TA181J is an example of a fixed inductor. It is suitable for use in a variety of consumer electronics, automotive electronic systems, high-end audio equipment, and professional audio applications. Its working principle involves creating a low-pass filter using inductance, which opposes any changes in the current, and a low-frequency LC filter created by connecting the component to capacitors in order to reduce noise and prevent damage to the components.
