As a new developed material, Fe-based nanocrystalline has good magnetic properties under medium-high frequency. Xianyu’s nanocrystalline CMC (common mode choke) core has permeability more than 10000 even the frequency reach 100kHz. We treat the cores by different annealing methods and make our nanocrystalline cores suitable for a variety of medium-high frequency applications.
