28R1127

Overview

The Leader Tech Inc. 28R1127 is a solid flat ferrite cable core designed for EMI suppression. It features a hinged design for easy installation around cables without disconnection. The component utilizes Ferrite material 28, providing an impedance of 151 Ohms at 100MHz according to DigiKey specifications, while other sources cite 188 Ohms at the same frequency. Internal dimensions are 23.50mm x 1.68mm (0.925" W x 0.066" H), and external dimensions are 28.58mm x 7.70mm (1.125" W x 0.303" H). The length is 24.89mm (0.980"). It is packaged in bulk quantities.

Feature Summary

• Hinged construction allows for quick installation on existing cables
• Solid flat profile minimizes spatial requirements
• Utilizes Ferrite 28 material for high-frequency noise attenuation

Applications

• Suppression of electromagnetic interference in data cables
• Noise reduction in communication line assemblies
• EMI filtering for flat ribbon cables

Procurement Notes

Verify the specific impedance value required for your application, as documentation varies between 151 Ohms and 188 Ohms at 100MHz. Confirm the internal width matches your cable thickness, noting slight variations in reported inner height (1.68mm vs 1.70mm). Ensure the hinged mechanism integrity is suitable for your deployment environment. Check RoHS compliance status if restricted substances are a concern.

Selection Notes

Select this component when a non-invasive, snap-on ferrite solution is needed for flat or round cables. The hinged design eliminates the need to thread cables through fixed cores. Compare the 151 Ohm versus 188 Ohm impedance ratings against your target noise spectrum. Ensure the physical dimensions accommodate the cable bundle diameter within the 23.50mm internal width constraint.

Part Context

This part belongs to the Leader Tech Ferrite Cable Cores category, specifically under the Solid Bar Ferrites or FerriShield series. It serves as an EMI/RFI mitigation component. The product is distinct from saddle beads like the SB28 series, offering a free-hanging, hinged form factor rather than an adhesive-mounted bead design.

Replacement Considerations

No officially confirmed substitute part numbers were found in the provided documentation. Users should verify compatibility with generic hinged ferrite cores by matching the 23.50mm internal width and similar impedance characteristics at 100MHz.
