2643180551

Overview

The Fair-Rite 2643180551 is a solid free-hanging ferrite core designed for flat cable EMI suppression. It accommodates multi-conductor flat cables with widths ranging from 12.7 mm to 77 mm. The component exhibits an impedance of 110 ohms at 25 MHz and 110 ohms at 100 MHz. Its internal dimensions are 34.80 mm width by 1.30 mm height, while external dimensions measure 40.01 mm width by 0.256 inch height.

Feature Summary

• Solid construction suitable for free-hanging installation on flat ribbon cables
• Engineered to suppress electromagnetic interference in multi-conductor applications
• Compatible with flat cable widths spanning 12.7 mm up to 77 mm

Applications

• Electromagnetic interference suppression for flat ribbon cables
• Multi-conductor signal line filtering
• Cable harness noise reduction

Procurement Notes

Verify the specific impedance rating and dimensional compatibility against your design requirements before procurement. Confirm that the flat cable width falls within the specified operational range of 12.7 mm to 77 mm. Ensure the mounting method aligns with the free-hanging design characteristics of this solid core component.

Selection Notes

Select this component when managing wide flat cables requiring robust EMI suppression without split-core mechanisms. The solid design provides consistent performance across the specified frequency range. Consider the physical clearance required for the free-hanging configuration during PCB or chassis layout planning.

Part Context

This part belongs to the Fair-Rite flat cable suppression core series, specifically engineered for high-density multi-conductor environments. It addresses noise issues in parallel data lines and power distribution networks where traditional round cores cannot accommodate the cable geometry effectively.

Replacement Considerations
