2643173851

Overview

Fair-Rite 2643173851 is a free-hanging split ferrite core designed for flat cable EMI suppression. It utilizes Material 43 and provides an impedance of 58 ohms at 100 MHz. The component features a circular inner diameter of 12.50 mm (0.492 inches) to accommodate cables. Its rectangular cross-section measures 16.50 mm in width and 2.00 mm in height, with an overall length of 10.31 mm (0.406 inches). This design allows for easy installation around existing wiring without disconnection.

Feature Summary

• Split construction enables installation on terminated cables
• Material 43 composition optimized for high-frequency noise suppression
• Free-hanging design facilitates flexible mounting configurations

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Signal line filtering in electronic assemblies
• Power cable noise reduction in compact devices

Procurement Notes

Verify the specific impedance value against your system requirements, as split cores are controlled for minimum impedance only. Confirm that the internal diameter accommodates the target cable bundle thickness. Ensure the material selection aligns with the frequency range of the noise being suppressed. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when working with flat cables requiring non-invasive noise reduction. The 12.50 mm inner diameter suits moderate cable bundles. Material 43 is suitable for frequencies above 10 MHz. Consider the physical dimensions to ensure adequate clearance within the enclosure. Verify that the split design does not compromise the mechanical integrity of the cable assembly.
