RC20B2480

Overview

The RC20B2480 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc., designed for flat ribbon cables. It features an internal aperture of 52 mm width by 1.5 mm height, accommodating specific flat cable geometries. The external dimensions are 80.8 mm in length, 28.6 mm in width, and 20.3 mm in height. Constructed from material grade 20 ferrite, it provides electromagnetic interference suppression. The unit utilizes a free-hanging installation type without adhesive backing.

Feature Summary

• Hinged design allows for easy clamping onto existing flat ribbon cables without disconnection.
• Specifically shaped internal aperture matches flat ribbon cable profiles for secure fitment.
• Free-hanging installation method eliminates the need for adhesives or mechanical fasteners.

Applications

• Electromagnetic interference suppression on flat ribbon data cables
• Signal integrity enhancement in high-speed digital circuits
• Compliance assistance for radiated emission standards

Procurement Notes

Verify the exact ferrite material grade (Grade 20) against your frequency-specific attenuation requirements. Confirm that the internal aperture dimensions (52 mm x 1.5 mm) precisely match the target flat cable thickness and width to ensure proper magnetic coupling. Check for RoHS compliance documentation if required by your assembly specifications.

Selection Notes

Select this component when dealing with wide flat ribbon cables rather than single round wires. Ensure the application environment does not require adhesive mounting, as this model relies on a free-hanging hinge mechanism. Compare internal dimensions carefully against similar models like FC20B2480 or FA20B2480 to distinguish between adhesive and non-adhesive variants.

Part Context

This part belongs to the Leader Tech ferrite clamp-on core family, specifically engineered for flat cable applications. It serves as a passive EMI suppression solution, distinct from snap-grip or box-style cores used for round conductors. The hinged construction facilitates retrofitting into existing cable assemblies.

Replacement Considerations

FC20B2480 offers identical dimensions but includes an adhesive backing. FA20B2480 shares the same physical footprint and hinge design but may differ in material composition or packaging details. Verify functional equivalence before substitution.
