RA28B0765

Overview

The RA28B0765 is a hinged flat cable ferrite clamp manufactured by LeaderTech Inc. It features an internal length of 13.9 mm and an internal height of 1.5 mm, designed for ribbon cables. The core material is designated as type 28, providing an impedance of 142 Ohms at 100 MHz. The unit includes adhesive for secure mounting and is supplied in bulk packaging.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing flat ribbon cables without disconnecting the circuit.
• Integrated adhesive backing ensures the ferrite core remains securely fixed to the target surface during operation.
• Solid rectangle construction provides consistent electromagnetic interference suppression across the specified frequency range.

Applications

• Suppression of common mode noise on parallel flat ribbon cables
• EMI mitigation in high-speed digital data transmission lines
• Noise filtering for peripheral interconnects in computing hardware

Procurement Notes

Verify that the specific order matches the RA28B0765 part number to ensure the inclusion of the adhesive feature, as non-adhesive variants exist within the same product family. Confirm compliance with RoHS directives if required for your assembly process. Check datasheet specifications for maximum operating temperature limits before final integration into the system design.

Selection Notes

Select this component when a permanent, non-removable EMI solution is preferred over reusable clamps. The 142 Ohm impedance at 100 MHz suits general-purpose digital noise reduction. Ensure the flat cable thickness does not exceed the 1.5 mm internal height clearance to allow proper closure of the hinge mechanism.

Part Context

This component belongs to the LeaderTech 28 series of ferrite materials, optimized for broadband absorption. It falls under the category of clamp-on cores specifically engineered for flat ribbon geometries rather than round wires or single conductors.

Replacement Considerations

RC28B3012 offers similar magnetic properties but lacks the integrated adhesive feature. FC28B0071 is a comparable size variant but requires separate mounting methods. Verify dimensional compatibility before substituting these alternatives.
