2661665702

Overview

Fair-Rite Products Corp. part number 2661665702 is a cylindrical solid ferrite core designed for electromagnetic interference suppression on cables. The component utilizes Fair-Rite Material 43, providing an impedance of 190 ohms at 100 MHz and 450 ohms at 25 MHz. It features a solid construction with free-hanging installation. Physical dimensions include an inner diameter of 0.375 inches (9.53 mm), an outer diameter of 0.687 inches (17.45 mm), and a length of 1.125 inches (28.58 mm).

Feature Summary

• Solid cylindrical design constructed from Material 43 for effective high-frequency noise attenuation.
• Free-hanging installation style allows for easy placement over existing cable assemblies without disconnection.
• Guaranteed minimum impedance specifications ensure consistent performance in EMI suppression applications.

Applications

• Suppression of common-mode noise on data and power cables.
• EMI filtering in electronic equipment wiring harnesses.
• Noise reduction on communication lines and peripheral connections.

Procurement Notes

Verify the specific impedance requirements against the Material 43 datasheet to ensure compatibility with the target frequency range. Confirm that the cable diameter falls within the 9.53 mm inner diameter tolerance. Check for RoHS compliance status if required by the end-product regulations. Ensure the solid form factor suits the physical constraints of the assembly compared to split-core alternatives.

Selection Notes

Select this component when a permanent, non-split ferrite solution is required for cables up to 9.53 mm in diameter. Material 43 is optimal for frequencies between 10 MHz and several hundred MHz. Compare against other Fair-Rite materials if the dominant noise frequency differs significantly from the 100 MHz specification. Consider the 17.45 mm outer diameter for clearance planning in tight enclosures.

Part Context

This part belongs to the Fair-Rite round cable core product line, specifically utilizing Material 43. It is distinct from split cores or axial beads. The solid construction differentiates it from openable designs, making it suitable for manufacturing stages where the cable cannot be threaded through a split ring after assembly.

FAQ

Is this ferrite core split or solid?

The 2661665702 is a solid cylindrical ferrite core, not a split or openable design.

What material composition does this part use?

It is manufactured using Fair-Rite Material 43, which provides specific magnetic properties optimized for mid-to-high frequency noise suppression.
