Do you know the general material of EMI common mode inductors?

EMI refers to electromagnetic interference. In simple terms, EMI common mode inductance is a common mode inductance product that is used to solve EMI in electronic products. So, do you know what material EMI common mode inductors are generally made of?

Common-mode inductors have three common core materials: manganese core, nickel core, and iron powder core. Among them, the characteristic of the nickel core material is that its impedance can be made relatively large, which is very suitable for EMI use. Seeing this, do you think the material of EMI common mode inductor is nickel core?

We say that the nickel core material is suitable for EMI use, and "suitability" does not mean "uniqueness". If we only look at the characteristics of the magnetic core without considering other factors, it is indeed that the common mode inductor made of nickel core is suitable for EMI. But in actual customer cases, it is impossible not to take other factors into consideration. On the contrary, we must analyze the real cause of the product EMI based on the actual situation in order to provide an accurate and effective solution. The reasons for EMI are very different in practice. Simply put, common mode inductors used for EMI may use manganese core magnetic cores, or they may use iron powder core magnetic cores, and they are not limited to nickel. Core magnetic core.

The core material does have a great influence on EMI. According to years of experience, the EMI effect of the core material of a well-known brand is generally much better. The main reason is that the quality of the brand magnetic core is relatively more stable and the consistency is better. Of course, specific cases need to be analyzed in detail.
