What is the effect of the size change of the chip common mode inductance package on the inductance performance?

As one of the most important products in chip inductors, chip common mode inductors play an irreplaceable role in many electronic devices. When we choose the chip common mode inductor, we will focus on its package size, so do you know what impact the change in the chip common mode inductor package size will have on the electrical performance?

The change in the package size of the patch common mode inductor will first have a direct impact on its installation on the circuit board. Of course, the effect of the size change on its electrical properties is the key. We can summarize it briefly:

1, the impact of size change on the inductance value: the change in the size of the chip common mode inductance package will first have an impact on the inductance value, in simple terms, the larger the package size, the larger the inductance value. Because the change of package size is accompanied by the change of core surface area, it will affect the change of inductance value.

2, the impact of size change on the inductor temperature stability: the impact of package size change on the inductor temperature stability is easy to be ignored, the increase or decrease of package size will inevitably be accompanied by the reduction or increase of the internal heat dissipation area of the inductor, which will inevitably affect the heat dissipation of the inductor, thus affecting the inductor temperature.

3, the impact of size change on inductance parameters: The impact of the change in the size of the chip common mode inductance package on the inductance is actually all aspects, which will lead to different parameters in all aspects of it. Therefore, we need to consider the actual application scenario requirements when choosing the chip common mode inductor.
