Fair-Rite has tooled several special core geometries in the 43 & 77 material for suppression of conducted EMI.

• These suppression cores are controlled for impedance only.The impedances listed are typical values. Single turns tests are performed on the 4193A Vector Impedance Analyzer with the shortest practical wire length.

• Performance curves for individual components can be viewed by clicking on the part number in the chart.

• For any non-catalog suppression core design feel free to contact our customer service or application group for feasibility and availability.

• The "C" dimension, the core length, can be modified to suit specific applications.

• Explanation of Part Numbers: Digits 1&2 = product class and 3&4 = the material grade.
