Fixed inductors are electronic components that can store energy in the form of magnetic fields when a current passes through them. The L0402R82AHN is an example of one such component. This article will examine its application field and discuss its working principle.

Application field

The L0402R82AHN is a small 7.3mm x 4.2mm surface mount chip inductor. This makes it ideally suited for a number of applications, such as the filtering of low-frequency signals, as well as the bypassing, decoupling, and smoothing of high-frequency signals. The inductor has an incredibly low DC resistance of only 0.3 ohms, which makes it perfect for these kinds of tasks.

The component also works great for reacting quickly to changes in circuit demand, and is perfectly suited for high-speed loading and unloading operations. For these reasons, it is widely used in automotive electronics, communication systems, consumer electronics, power filtering, and more.

Working principle

Similar to how passives like resistors work, the L0402R82AHN inductor works by converting electrical energy into magnetic energy. It does this by creating a magnetic field in its core which opposes the applied current. This magnetic field stores the energy and stops the current from flowing any further. As a result, the inductor is able to maintain a steady output current.

The L0402R82AHN uses a ferrite core to store the generated magnetic field. This material, along with the number of turns in the coil, has a direct influence on the inductance of the component. The higher the inductance, the stronger the magnetic field will be.

In terms of usage, when an alternating current is applied to the inductor, a varying magnetic field is generated. This magnetic field then interacts with the inductor core, which is then converted into a mechanical force. This force causes the inductor core to vibrate, producing an oscillating electrical output.

Conclusion

The L0402R82AHN is a small, surface-mount chip inductor which can be used for a number of applications. It is highly suited to filtering and smoothing low- and high-frequency signals, as well as reacting quickly to changes in circuit demand. In terms of its working principle, it works by converting electrical energy into a magnetic field, which is then converted into a mechanical force and oscillation.
