SM28R1260

Overview

The SM28R1260 is a solid flat ferrite cable core manufactured by LeaderTech, designed for electromagnetic interference suppression. It features an impedance of 237 Ohms at a test frequency of 100 MHz. The component has an internal length of 25.7 mm and an internal height of 1.3 mm to accommodate ribbon cables. External dimensions include a length of 32 mm, width of 28.6 mm, and height of 8.4 mm. It is supplied in bulk packaging.

Feature Summary

• Solid construction provides structural integrity for flat ribbon cable applications.
• Integrated adhesive backing facilitates secure shock mount installation.
• Hinged design allows for easy engagement with cable assemblies without disconnection.

Applications

• Electromagnetic interference reduction in electronic devices
• Shielding for flat ribbon cable assemblies
• Signal integrity enhancement in high-speed data lines

Procurement Notes

Verify the specific impedance value of 237 Ohms at 100 MHz against your system requirements before ordering. Confirm that the internal dimensions (25.7 mm length, 1.3 mm height) match the target cable thickness and width. Ensure the adhesive mounting style aligns with your assembly process capabilities. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a fixed-impedance solution for flat ribbon cables is required. The 237 Ohm rating targets specific noise frequencies at 100 MHz. Consider the external footprint (32 x 28.6 x 8.4 mm) for spatial constraints. The hinged mechanism simplifies installation compared to split cores, reducing assembly time while maintaining consistent magnetic coupling.
