RA28B3012

Overview

The RA28B3012 is a hinged ferrite clamp-on core designed for flat ribbon cables. It belongs to the RA28 series and utilizes material grade 28. The component features an adhesive backing for secure attachment. External dimensions are 64.5 mm in length, 33.3 mm in width, and 1.5 mm in height. The internal length measures 64.5 mm. The external depth is specified as 0.7 mm.

Feature Summary

• Hinged snap-on design allows installation on existing flat cable assemblies without disconnection.
• Integrated adhesive bottom ensures permanent mounting to chassis or equipment surfaces.
• Material grade 28 provides specific impedance characteristics for high-frequency noise suppression.

Applications

• Suppression of electromagnetic interference on flat ribbon cables within electronic devices.
• EMI mitigation in computer peripheral connections and data transmission lines.
• Noise reduction in internal wiring harnesses of consumer electronics.

Procurement Notes

Verify the exact part number against manufacturer documentation to ensure compatibility with specific flat cable widths. Confirm that the adhesive type meets environmental requirements for the intended application. Check RoHS compliance status if required by regional regulations. Ensure the selected variant matches the required impedance profile for the target frequency range.

Selection Notes

Select this component when dealing with flat ribbon cables requiring fixed, non-removable EMI protection. The hinged design facilitates retrofitting onto assembled cables. Consider the physical dimensions to ensure adequate clearance within the enclosure. Verify that the adhesive strength is sufficient for the mounting surface material and operating temperature conditions.

Part Context

This component is part of Leader Tech's FerriShield line of ferrite accessories. It falls under the category of cable ferrites and snap-on cores. The RA28 series is engineered for broadband noise suppression applications. It serves as a passive filtering solution for high-speed digital signals carried by flat cables.

Replacement Considerations

FA28B3012 is a documented alternative from the same manufacturer offering similar form factor and material properties. Cross-reference dimensional tolerances and adhesive specifications before substitution to ensure mechanical fit.
