FD28B3012

Overview

The FD28B3012 is a hinged ferrite clamp manufactured by Leader Tech Inc., designed for flat ribbon cables. It utilizes material grade 28 to provide electromagnetic interference suppression. The component features an enclosure shielding solution with specific dimensional attributes: an internal length of 64.5 mm, an internal height of 1.5 mm, and an external width of 33.3 mm. The external dimensions include a length of 82.8 mm and a height of 17 mm. This snap-on core allows for easy installation on existing cable assemblies without disconnecting the signal path.

Feature Summary

• Hinged design enables rapid installation onto flat ribbon cables without breaking electrical connections.
• Constructed from high-permeability ferrite material to absorb high-frequency noise.
• Enclosed structure provides comprehensive coverage around the cable bundle.

Applications

• Suppression of electromagnetic interference in flat ribbon cable assemblies
• EMI mitigation in computer peripheral interconnects
• Noise reduction in industrial control panel wiring

Procurement Notes

Verify the exact material grade and impedance specifications against the official manufacturer datasheet before procurement. Confirm that the internal dimensions accommodate the specific thickness and width of the target flat ribbon cable. Ensure the hinged mechanism functions correctly for the intended application environment. Check for RoHS compliance requirements if applicable to the final product assembly.

Selection Notes

Select this component when a non-intrusive EMI solution for flat cables is required. The hinged style is preferred over split cores for repeated access or secure retention. Compare the internal height and width against the cable bundle size to ensure a snug fit. Consider the frequency range of the noise source to verify compatibility with the ferrite material properties.

Part Context

This part belongs to the Leader Tech ferrite clamp family, specifically engineered for flat ribbon applications. It serves as an alternative to adhesive-mounted beads or sleeve cores where mechanical retention via a hinge is necessary. The product line focuses on providing effective RFI/EMI suppression for modern electronic interconnects.

Replacement Considerations

Cross-reference with FC28B3012 if adhesive mounting is acceptable instead of hinged. Verify dimensional compatibility with other flat cable ferrites from different manufacturers if supply constraints exist.

FAQ

Is the FD28B3012 suitable for round cables?

No, it is specifically shaped for flat ribbon cables. Using it on round cables may result in improper fit and reduced effectiveness.

Does the hinge mechanism affect the EMI performance?

The hinge is designed to maintain close contact between the core halves to ensure continuous magnetic circuit integrity for effective noise absorption.
