2643168051

Overview

Fair-Rite 2643168051 is a snap-on ferrite core designed for flat cable EMI suppression. It utilizes Material 43 and provides an impedance of 265 ohms at 100 MHz. The component features a free-hanging design with specific dimensional constraints: an inner diameter of 33.20 mm, an outer width of 52.90 mm, an outer height of 12.50 mm, and a length of 1.125 inches (28.58 mm).

Feature Summary

• Snap-on construction allows for easy installation on existing cables without disconnection.
• Material 43 composition provides high magnetic permeability for effective noise attenuation.
• Free-hanging design facilitates integration into various chassis or panel mounting configurations.

Applications

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

Procurement Notes

Verify the exact material grade and impedance specifications against the manufacturer's current datasheet before finalizing procurement. Ensure that the physical dimensions, particularly the inner diameter and cross-sectional profile, are compatible with the target cable bundle to guarantee proper fit and effective performance.

Selection Notes

Select this component when flat cable geometry requires a snap-on solution rather than a split-core clamp. Material 43 is suitable for frequencies ranging from approximately 1 MHz to 100 MHz. Confirm that the required impedance value meets the system's noise suppression requirements at the specific frequency of interest.

Part Context

This part belongs to Fair-Rite's Snap-It series of ferrite cores, which are engineered for rapid deployment on cables. The 2643168051 model specifically addresses the need for suppressing common-mode noise on wider flat cables where standard round cores are unsuitable due to shape constraints.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with alternative suppliers by matching Material 43 composition, impedance characteristics, and physical dimensions.
