What is the effect of the chip inductor size on the inductance performance?

As a widely used inductor type, chip inductor plays a very important role in many electronic devices. When we do the selection of the chip inductor, we will require that we must be clear about the package size of the chip inductor used, because the size of the chip inductor is not only directly related to whether it can be normally applied in production, but also has some impact on the electrical performance of the chip inductor. This article will give you a brief introduction to the impact of the size of the chip inductor on the electrical performance.

The impact of the size of the chip inductance on the performance of the inductance parameters is mainly the impact on the inductance value, saturation current and loss, such as:

1,Influence on the inductance value of the patch: Through the calculation formula of the inductance value, we conclude that the size of the cross-sectional area of the wire has an impact on the inductance value. The size of the chip inductor will inevitably affect the cross-sectional area of its internal wire. Under normal circumstances, the smaller the size of the chip inductance, then its inductance value will be relatively large.

2, the impact on the saturation current of the chip inductor: the saturation current mainly refers to when the current in the inductor reaches a certain peak, the chip inductor will not be able to continue to increase the current. In general, the smaller the size of the chip inductor, the smaller its retention current is.

3, the impact on the chip inductance loss: the chip inductance loss mainly refers to the loss of electrical energy into heat during the operation of the circuit board. Because the size of the chip inductor is smaller, the cross-sectional area of its internal wire is smaller, so the resistance of the chip inductor will increase at this time, and the heat loss will be more.

In short, the change in the size of the chip inductor has an impact on the electrical performance, so we must ensure the correctness of the package size selection when choosing the chip inductor.For more information, please contact us at sales@xfullstar.com
