SM28R1575

Overview

The SM28R1575 is a solid flat ferrite cable core manufactured by LeaderTech, designed for electromagnetic interference suppression. It utilizes material grade 28 and provides an impedance of 160 ohms at a test frequency of 100 MHz. The component features a hinged design with adhesive backing for secure attachment to ribbon cables. Its physical dimensions include an internal length of 34.4 mm, an external length of 40 mm, an external width of 28.6 mm, an internal height of 1.3 mm, and an external height of 8.4 mm.

Feature Summary

• Solid flat construction with integrated adhesive shock mount for direct cable attachment
• Hinged design allows for easy installation around existing flat ribbon cables without disconnection
• Utilizes ferrite material grade 28 for effective high-frequency noise attenuation

Applications

• Suppression of electromagnetic interference on flat ribbon cables in electronic assemblies
• Noise reduction in data transmission lines within computer peripherals
• EMI mitigation in industrial control systems utilizing flat cabling

Procurement Notes

Verify the specific impedance value of 160 ohms at 100 MHz against system requirements. Confirm that the internal dimensions accommodate the target ribbon cable thickness and width. Ensure the adhesive type is compatible with the operating environment and cable surface material to maintain mechanical integrity during operation.

Selection Notes

Select this component when flat ribbon cable EMI suppression is required without breaking circuit continuity. The hinged mechanism simplifies retrofitting compared to split cores. Material grade 28 determines the frequency response characteristics; verify compatibility with the noise spectrum. The adhesive mounting eliminates the need for additional fasteners or clips.

Part Context

This part belongs to the LeaderTech ferrite cable core product line, specifically the solid flat series. These components are categorized under ferrites and are distinct from round snap-on cores or gasket-style shielding products. The SM28R1575 is engineered for applications requiring compact, low-profile noise suppression solutions for flat conductors.

Replacement Considerations

Cross-reference with other LeaderTech SM28R series parts if different impedance or dimensional constraints apply. Verify that substitute flat ferrite cores maintain the same hinged configuration and adhesive specifications to ensure identical installation procedures and mechanical retention.
