Mesiongbei supply a wide range of ferrite cores with excellent impedance performance for EMI mitigation and suppression.

While the ferrite's shape factor (ratio between the middle diameter and cross-sectional area) will largely determine the impedance, other variables should be considered during the ferrite core selection and testing process. These variables include the device's problematic frequency, length of the cable, location of the ferrite on the cable, cable turns, type of noise to be suppressed (common mode vs differential mode), as well as the formulation of the ferrite material that will work best for the target frequency.

Meisongbei offers an extensive array of ferrites including split clamp type, sleeve and toroidal shapes, flat cable cores.
