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.
