Nanocrystalline Common Mode Power Line Chokes

Würth Elektronik Nanocrystalline Common Mode Power Line Chokes are constructed with a nanocrystalline core material that exhibits a permeability about 10x higher than that of ferrite cores. The WE-CMANC series is AEC-Q200 compliant, while the WE-CMBNC series is standard. The chokes provide improved isolation through the plastic case and winding spacer, and high and stable inductance values at high temperatures. Specifications include a maximum operating temperature rating of +125°C, a 1kHz to 300MHz frequency range, and a compact design. Würth Elektronik Nanocrystalline Power Line Chokes are suitable for power electronics, powerline input and output filters, radio interference suppression in motors, and suppression for common mode noise.
