2643001301

Overview

Fair-Rite 2643001301 is a solid round ferrite cable core from the 26 series, utilizing Material 43 for EMI suppression. It features an impedance of 48 ohms at 100 MHz and operates within a frequency range of 25 MHz to 300 MHz. The component has an inner diameter of 1.78 mm, an outer diameter of 3.55 mm, and an external length of 3.25 mm. Packaged in bulk, it serves as a shield bead for suppressing electromagnetic interference on cables.

Feature Summary

• Solid round design for secure cable mounting
• Material 43 composition for high-frequency noise attenuation
• Shield bead configuration for direct cable application

Applications

• Electromagnetic interference suppression
• Cable shielding applications
• High-frequency signal integrity maintenance

Procurement Notes

Verify the specific impedance value of 48 ohms at 100 MHz against project requirements. Confirm that the 1.78 mm inner diameter accommodates the target cable gauge. Ensure Material 43 characteristics align with the intended operating frequency range of 25 MHz to 300 MHz. Check RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a solid, non-split ferrite bead is required for permanent installation. Material 43 is suitable for frequencies above 25 MHz. The small dimensions make it appropriate for tight spaces where larger cores cannot fit. Verify that the cable diameter matches the 1.78 mm bore size before ordering.

Part Context

This part belongs to Fair-Rite's 26 series of ferrite cable cores. The series includes various shapes and materials tailored for different EMI suppression needs. Material 43 is a common choice for general-purpose noise reduction in digital and RF circuits. The 26 series offers standardized dimensions for easy integration into existing designs.
