What are the conditions under which the inductance of a one-piece power inductor is affected?
Editor: Gujing Electronics.
As a particularly important inductive component, the inductance of the one-piece power inductor is an important consideration for the selection. There are often inquiries about the inductance of inductors, but today we will briefly discuss what causes the inductance of one-piece power inductors.
1. The influence of the number of turns wound by the coil on the inductance: the inductance coil is wound less than one turn, which will affect the use. In other words, the more turns the coil is wound, the greater the inductance of the one-piece power inductor. In other words, when choosing an inductor, it is also necessary to select the corresponding inductance according to the actual application requirements, and not only pursue a large inductance.
2. The influence of the working frequency on the inductance: that is to say, the inductance of the inductance will change with the change of the working frequency. In the low frequency band, the inductance of the common mode inductor is relatively large;In the high frequency band, the inductance will be smaller.
3. The influence of temperature on the inductance: the temperature will also have a certain impact on the inductance of the integrated power inductor. As the temperature increases, the permeability of the core material decreases, which causes the inductance to decrease.
4. The influence of inductance materials on inductance: It is easy to ignore this, and the production materials of one-piece power inductors will also have an impact on inductance. Therefore, sometimes we can improve the sensitivity by adjusting the production materials.
These are some of the reasons why it may affect the inductance of one-piece power inductors, and what other reasons do you know?Feel free to chat with us**.
