When selecting an I-chip inductor, we usually focus on its package size and electrical performance. Many people are curious about a question - does the package size of the I-chip inductor have any effect on its electrical performance?In this article, we will briefly ** this question.
The first thing to tell you is that the package size of the I-chip inductor has an impact on its electrical performance. The structure of the inductor seems simple, but in fact, every small detail change will bring about a change in electrical performance. The influence of inductor package size on electrical performance is mainly manifested in the following aspects:
1) Influence on inductance value: Simply put, when the package size is relatively large, the inductance value of the inductance is generally relatively large. Of course, here we are talking about the general situation. Because we can also adjust the inductance process to upgrade the inductance value of the inductor with a small package size.
2) Influence on quality factors: quality factors are indicators to measure inductance loss, which are related to factors such as coil resistance and cut-off loss. In general, the smaller the package size of the inductor, the easier it is to improve the quality factor.
3) Influence on saturation current: We know that when the number of turns of the coil and the length of the magnetic circuit are fixed, the larger the cross-sectional area of the core material, the greater the saturation current. Therefore, the saturation current of the inductor can be increased by using a larger package size.
Therefore, changes in the package size of an I-chip inductor will have an impact on its electrical properties. In actual use, we need to select the appropriate package of I-beam chip inductors according to the specific use requirements.
