Product Summary

Wurth Electronics has a common mode choke coil "WE-CMBNC" for power lines that uses "Nanocrystalline" as a ferrite core material. Compared to common mode choke coils that use conventional ferrite cores such as "NiZn" and "MnZn", WE-CMBNC is characterized by "small size", "light weight" and "low loss".

From the comparison table above, it can be seen that the magnetic permeability μ is a large value compared to other materials. Inductance can be obtained with a small number of turns due to high magnetic permeability, and Rdc is also small for low loss. In terms of temperature characteristics, one of the features is that it can maintain a stable inductance value in a high-temperature environment.

Can be used in a wide range of frequencies from low frequencies to several 100MHz

As shown in the frequency range for each material in the table below, Nanocrystalline can be used in a wide range of frequencies from low frequencies to several 100 MHz and can be used in a wide range of applications. Comparing the performance of ”7448031002 (Nanocrystalline)”, which has similar characteristics to the conventional product ”7448258022 (NiZn)”, the volume ratio is about 50% smaller and Rdc is less than half. From this, it is possible to make the most of the merits in terms of design points such as "miniaturization" and "low loss".
