2643200101

Overview

Fair-Rite 2643200101 is a solid round cable ferrite core from the 26 series, utilizing Material 43. It features an inner diameter of 1.3 mm and an outer diameter of 3.5 mm. The component has an external length of 3.25 mm and provides an impedance of 40 ohms at a test frequency of 100 MHz. It operates within a frequency range of 25 MHz to 300 MHz and is packaged in bulk quantities.

Feature Summary

• Solid round cable core design for direct wire clamping
• Material 43 composition optimized for high-frequency noise suppression
• Impedance characteristic of 40 ohms at 100 MHz

Applications

• EMI suppression on signal cables
• Common mode choke implementation
• High-frequency noise filtering in electronic assemblies

Procurement Notes

Verify the specific Material 43 designation and dimensional tolerances against the official Fair-Rite datasheet before integration. Confirm that the 1.3 mm inner diameter accommodates the target cable insulation thickness without mechanical stress. Ensure compliance with RoHS requirements as indicated in manufacturer documentation.

Selection Notes

Select this part when a compact, solid round core is required for cables up to 1.3 mm in diameter. Material 43 is suitable for applications requiring effective attenuation in the 25 MHz to 300 MHz range. Compare physical dimensions against available space constraints and verify impedance needs at the specific operating frequency.

Part Context

The 2643200101 belongs to the Fair-Rite 26 series of EMI suppression cores. This series includes various shapes such as flat ribbon, split, and toroidal options. The 26 prefix indicates the shape family, while the material number 43 defines the magnetic properties for broadband noise reduction.

Replacement Considerations

Check Fair-Rite's cross-reference list for alternative part numbers with identical dimensions or compatible impedance curves. Verify that any substitute maintains the same Material 43 specification to ensure equivalent high-frequency performance characteristics.
