SM28B2002

Overview

The SM28B2002 is a solid flat ribbon cable ferrite core manufactured by Leader Tech Inc. It features an impedance of 109 Ohms at a test frequency of 100 MHz and utilizes material grade 28. The component has internal dimensions of 5.08 mm width by 7.6 mm height, with external dimensions measuring 15.49 mm in width and 23.88 mm in height. The total length is 15.49 mm. This snap-on design allows for easy installation on flat ribbon cables to suppress electromagnetic interference.

Feature Summary

• Snap-on hinged design for secure attachment to flat ribbon cables
• Solid construction utilizing high-permeability material grade 28
• Optimized geometry for suppressing common-mode noise on interconnects

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Signal integrity enhancement in electronic enclosures
• Cable filtering for data transmission lines

Procurement Notes

Verify the specific impedance value and material grade against the official datasheet before procurement. Confirm that the internal dimensions match the target ribbon cable thickness and width. Ensure compliance with RoHS requirements if applicable to the end application. Check for any specific ordering suffixes that may indicate packaging variations or material certifications.

Selection Notes

Select this component when a snap-on solution is required for flat ribbon cables rather than split cores. Consider the 109 Ohm impedance rating at 100 MHz to ensure effective attenuation for the target noise frequencies. Evaluate the physical constraints to ensure the external dimensions fit within the available space in the electronic assembly.
