SM28R1127

Overview

The SM28R1127 is a solid flat ferrite cable core manufactured by Leader Tech Inc. It features a hinged snap-on design for easy installation on ribbon cables. The component utilizes Material 28, providing an impedance of 188 Ohms at a test frequency of 100 MHz. Physical dimensions include an overall length of 31.00 mm (1.220 inches), with internal dimensions of 23.50 mm width and 1.70 mm height.

Feature Summary

• Hinged snap-on design facilitates quick installation on flat ribbon cables without disconnection
• Constructed from Material 28 ferrite composition for specific high-frequency attenuation characteristics
• Solid flat form factor designed to accommodate standard ribbon cable geometries

Applications

• High-speed data transmission line noise suppression
• Embedded electronics cable assembly EMI mitigation
• Flat ribbon cable signal integrity enhancement

Procurement Notes

Verify the exact impedance value against the manufacturer's current datasheet, as sources indicate 188 Ohms at 100 MHz. Confirm that the hinged design matches the target cable thickness. Ensure Material 28 specifications align with required frequency performance. Check RoHS compliance status directly with the supplier documentation before integration.

Selection Notes

Select this component when a non-invasive solution for flat ribbon cables is required. The hinged design allows for retrofitting without breaking circuit continuity. Material 28 selection depends on the specific frequency range of interference. Verify physical clearance around the cable path to accommodate the external dimensions of the core housing.

Part Context

This part belongs to the Leader Tech solid flat ferrite cable core series. These components are engineered for electromagnetic interference suppression in compact electronic assemblies. The series offers various material compositions and dimensions to suit different cable sizes and frequency requirements.

Replacement Considerations

Cross-reference with other Material 28 flat ferrite cores from Leader Tech if dimensional constraints differ. Verify that substitute parts maintain the same hinged snap-on mechanism and impedance profile at 100 MHz to ensure equivalent noise suppression performance.
