2643005701

Overview

Fair-Rite 2643005701 is a cylindrical ferrite cable core designed for EMI suppression. It utilizes Material 43, providing an impedance of 120 ohms at 100 MHz across a frequency range of 25 MHz to 300 MHz. The component features an outer diameter of 5.1 mm (0.200 inches), an inner diameter of 2.3 mm (0.090 inches), and a length of 12.7 mm (0.500 inches).

Feature Summary

• Solid cylindrical design for snap-on installation around cables.
• Material 43 composition optimized for high-frequency noise attenuation.
• Provides significant impedance in the 25 MHz to 300 MHz spectrum.

Applications

• Suppression of electromagnetic interference on data cables.
• Noise reduction on power supply lines.
• EMI filtering for communication interface cables.

Procurement Notes

Verify that the target cable diameter falls within the specified inner diameter limits to ensure proper fit. Confirm that the application frequency aligns with the material's effective range. Check RoHS compliance status if required by specific regulatory standards. Ensure the solid bead design meets mechanical constraints compared to split-core alternatives.

Selection Notes

Select this part when a fixed, non-removable ferrite solution is required for cables fitting the 2.3 mm bore. Material 43 is suitable for higher frequency applications compared to Material 31. Consider the physical length and diameter constraints of the assembly space. Verify that the 120 ohm impedance level matches the circuit's noise profile requirements.

Part Context

This component belongs to Fair-Rite's standard round cable core series. It serves as a passive filter element to absorb high-frequency noise energy. The product is distinct from split cores or flat ribbon cable beads. It represents a common form factor for general-purpose EMI suppression in electronic assemblies.

Replacement Considerations

Direct substitutes include other Material 43 cylindrical cores with similar dimensions, such as Fair-Rite 2643001301. Cross-reference impedance values at 100 MHz to ensure equivalent performance. Verify dimensional compatibility before substitution.
