Filter and Material Behavior
Common mode chokes with dual winding chambers are charatcerized by a higher attenuation maximum compared to those with a single winding chamber. At the same time, this attenuation maximum is shifted to higher frequencies.
By choosing the right core material for common mode chokes, the desired attenuation curve depending on the frequency can be chosen. While manganese-zinc has its attenuation maximum at lower frequencies, it is higher for nickel-zinc. Nanocrystalline core material and the combination of manganese-zinc with nickel-zinc exhibit broader attenuation behavior.
