28R1953

Overview

The Leader Tech Inc. 28R1953 is a hinged snap-on cable ferrite core designed for EMI suppression in ribbon cable applications. It features a flat core geometry with an inner dimension of 44.00 mm width by 1.50 mm height and an outer dimension of 49.60 mm width by 7.30 mm height. The component provides an impedance of 109 Ohms at 100 MHz, facilitating effective noise reduction for high-speed data lines.

Feature Summary

• Hinged snap-on design allows installation on cables without disconnecting connectors
• Flat core profile accommodates ribbon cables and flat wiring harnesses
• Integrated case structure protects the ferrite material and maintains alignment

Applications

• Suppression of electromagnetic interference on ribbon cables
• Noise filtering for high-speed digital signal transmission lines
• EMI mitigation in computer peripheral connections and internal bus architectures

Procurement Notes

Verify the specific impedance value of 109 Ohms at 100 MHz against your system's noise frequency requirements. Confirm that the inner dimensions of 44.00 mm by 1.50 mm match the physical cross-section of the target ribbon cable to ensure proper fit and magnetic coupling efficiency during procurement.

Selection Notes

Select this component when retrofitting existing cable assemblies where disconnection is impractical due to the snap-on mechanism. The flat geometry is specifically suited for ribbon cables rather than round wires. Ensure the operating environment does not exceed the thermal limits specified in the official datasheet for standard ferrite materials.

Part Context

This part belongs to the Leader Tech Ferrishield series of cable filters. It serves as a passive EMI/RFI suppression device within the broader category of electronic interconnect accessories. The product is manufactured by Leader Tech Inc., specializing in shielding and absorption solutions for electronic systems.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with any alternative hinged ferrite cores by matching the inner width, height, and impedance characteristics at the target frequency.
