Fair-Rite 2643665702 is a solid round ferrite cable core designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 200 Ohms at 100 MHz. The component features a cylindrical geometry with an inner diameter of 9.53 mm (0.375 inches), an outer diameter of 17.45 mm (0.687 inches), and a length of 28.58 mm (1.125 inches). It is rated for operation between -55°C and +125°C. The part is RoHS compliant and classified under HTSUS code 8547.10.8000.
Verify the specific Material 43 designation and impedance tolerance against the official Fair-Rite datasheet prior to integration. Confirm that the 9.53 mm inner diameter accommodates the target cable bundle without excessive clearance. Ensure environmental ratings meet operational temperature requirements.
Select this component when Material 43 characteristics are required for the target frequency range. The 9.53 mm bore size dictates compatibility with specific cable diameters. Consider the solid design for applications requiring fixed positioning without split mechanisms.
This part belongs to the Fair-Rite 26 series of round cable cores. It is distinct from split cores due to its solid construction, which requires threading the cable during assembly. The 200 Ohm impedance at 100 MHz positions it for specific high-frequency suppression tasks compared to lower or higher impedance variants.
Direct substitutes must match the 9.53 mm inner diameter, 17.45 mm outer diameter, 28.58 mm length, and Material 43 composition. Verify impedance curves rather than single-point values for accurate functional equivalence.
