2643000701

Overview

Fair-Rite 2643000701 is a solid round ferrite cable core from the 26 series, utilizing Material 43. It functions as an EMI suppression shield bead with an impedance of 125 ohms at 100 MHz. The component features a 1.3 mm inner diameter, 3.51 mm outer diameter, and 12.70 mm length. Designed for free-hanging installation, it operates within a temperature range of -55°C to +90°C.

Feature Summary

• Solid construction provides structural integrity for direct cable clamping
• Material 43 composition optimizes high-frequency noise attenuation
• Free-hanging design allows flexible mounting on cables without hardware

Applications

• Suppression of electromagnetic interference on signal cables
• Common-mode noise reduction in data transmission lines
• EMI filtering for power supply input/output wiring

Procurement Notes

Verify the specific impedance value required for your application against the datasheet, as distributor listings may vary between 120 and 125 ohms at 100 MHz. Confirm that the 1.3 mm inner diameter accommodates the target cable gauge. Ensure compliance with RoHS directives if applicable to your manufacturing process.

Selection Notes

Select this part when a compact, solid ferrite bead is needed for cables up to 1.3 mm in diameter. Material 43 is suitable for frequencies above 25 MHz. Compare dimensions against available space constraints and ensure the thermal rating of -55°C to +90°C meets environmental requirements.

Part Context

The 26 series represents Fair-Rite's standard line of solid round ferrite cores. These components are widely used for general-purpose EMI suppression. The 2643000701 variant specifically combines Material 43 properties with a small form factor, making it distinct from split-core or larger multi-aperture designs in the same family.
