2646540202

Overview

The Fair-Rite Products Corp. 2646540202 is a solid, free-hanging ferrite core designed for round cable EMI suppression. It utilizes Material 46 to provide an impedance of 106 Ohms at 100 MHz. The component features a circular design with an inner diameter of 0.250 inches (6.35 mm), an outer diameter of 0.562 inches (14.28 mm), and a length of 0.530 inches (13.46 mm).

Feature Summary

• Solid construction for stable mechanical integrity on cables.
• Material 46 composition optimized for high-frequency noise attenuation.
• Free-hanging installation method allows easy placement on existing wiring.

Applications

• Suppression of electromagnetic interference on round data cables.
• Noise reduction in communication system interconnects.
• Filtering common-mode currents on power supply lines.

Procurement Notes

Verify the specific Material 46 designation against current Fair-Rite datasheets to ensure compatibility with target frequency ranges. Confirm that the 106 Ohm impedance specification meets the required noise suppression levels for the intended application environment. Check RoHS compliance status if restricted substances are a concern.

Selection Notes

Select this part when a solid, non-split core is required for round cables up to 6.35 mm in diameter. Material 46 is suitable for frequencies typically above 10 MHz. Ensure the physical dimensions fit within the available space constraints of the assembly.

Part Context

This component belongs to the Fair-Rite 26 series of round cable cores. These components are widely used in electronics manufacturing to mitigate radiated emissions from cables acting as unintentional antennas. The 2646540202 variant specifically targets applications requiring robust, permanent attachment without clamping mechanisms.

Replacement Considerations

Direct substitutes must match the 106 Ohm @ 100 MHz impedance and Material 46 composition. Alternative Fair-Rite part numbers with identical dimensions and material properties may be considered if availability differs.
