2643300101

Overview

Fair-Rite 2643300101 is a solid round ferrite cable core utilizing Material 43 for EMI suppression. It provides an impedance of 200 Ohms at 100 MHz, with a test frequency of 100 MHz and effective operation between 25 MHz and 300 MHz. The component features a 2.25 mm inner diameter, 7.6 mm outer diameter, and 15.1 mm length. Designed as a shield bead, it weighs 2.100 g and is RoHS compliant.

Feature Summary

• Solid round construction designed for free-hanging installation on cables
• Material 43 composition optimized for high-frequency noise attenuation
• Shield bead configuration providing significant impedance at 100 MHz

Applications

• Signal filtering in electronic assemblies
• EMI suppression on data and power cables
• Noise reduction in high-frequency signal lines

Procurement Notes

Verify the specific impedance requirement matches the application's noise profile, as this component offers 200 Ohms at 100 MHz. Confirm that the 2.25 mm inner diameter accommodates the target cable gauge without excessive clearance. Ensure the solid design aligns with the assembly process, as it requires manual placement rather than snap-on mechanisms. Check RoHS compliance status if restricted substances are a concern.

Selection Notes

Select this part when a fixed impedance value is required for broadband noise suppression. The Material 43 composition is suitable for frequencies above 25 MHz. Consider the physical dimensions to ensure adequate space around the cable. This solid core type is appropriate for permanent installations where snap-on access is not needed.
