WE-CMBNC Common Mode Nanocrystalline Chokes

Würth Elektronik WE-CMBNC Common Mode Power Line Chokes are constructed with a nanocrystalline core material that exhibits high permeability, about 10 times higher than ferrite cores. The WE-CMBNC series offers broadband suppression characteristics that can reduce mains interference down to the low kHz range. Other features include high and stable inductance values at high temperatures, small size, frequency range up to 300MHz, and high rated currents. Applications for Würth WE-CMBNC Common Mode Power Line Chokes are power electronics, powerline input and output filters, radio interference suppression in motors, and suppression for common-mode noise.
