Crystal Clear Frequencies.
Common Mode Power Line Chokes
The Würth Elektronik WE-CMBNC is a VDE certified series of common mode chokes with a highly permeable nanocrystalline core material. Despite the small size, it delivers oustanding broadband attenuation performance, high rated currents and low DC resistance values. Low profile and high voltage ratings can also be realized by the common mode chokes of the WE-CMB family.
