SM28B1101

Overview

The Leader Tech SM28B1101 is a solid ferrite suppressor designed for flat ribbon cables. It features a hinged snap-on design with an impedance of 133 Ohms. The component measures 22.9 mm in inside length and 28 mm in outside length, with a width of 1.5 mm. It utilizes 28 material composition and includes a high-tack adhesive mounting pad for secure installation prior to cable termination.

Feature Summary

• Hinged snap-on configuration for easy installation on flat ribbon cables
• High-tack adhesive base ensures secure mounting without additional hardware
• Solid ferrite construction provides effective electromagnetic interference suppression

Applications

• Suppression of noise on flat ribbon cables in electronic assemblies
• EMI mitigation in data transmission lines requiring snap-on ferrites
• Installation on cables prior to final termination processes

Procurement Notes

Verify the specific impedance rating of 133 Ohms matches your EMI suppression requirements. Confirm the physical dimensions, particularly the 1.5 mm width and 22.9 mm inner length, fit the target ribbon cable. Ensure the adhesive backing is compatible with the installation surface. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a snap-on ferrite is preferred over split-core types for permanent installations. The 133 Ohm impedance suits specific frequency ranges; verify against your noise spectrum. The adhesive base simplifies assembly but requires clean surfaces. Consider the 28 material composition for its magnetic properties relative to your application's frequency needs.

Part Context

This part belongs to the FerriShield line of solid ferrite suppressors from Leader Tech. These components are engineered for rectangular solids and often include optional shock-mount adhesive foam bases. The series is designed for robust EMI/RFI protection in compact electronic environments where ribbon cables are prevalent.

Replacement Considerations
