28S2827-210

Overview

The Laird-Signal Integrity Products 28S2827-210 is a split ferrite core designed for flat ribbon cables. It features a clip-together design where two units form one assembly. The component utilizes Material 28, providing an impedance of 120 Ohms at 100MHz. Internal dimensions are 0.669 inches wide by 0.037 inches high (17.00mm x 0.94mm). External length measures 21mm. It is classified as a free-hanging cable ferrite suitable for EMI suppression in signal integrity applications.

Feature Summary

• Split core construction allows installation on existing cables without disconnection
• Clip-together design ensures secure mechanical retention around the conductor
• Material 28 composition provides specific high-frequency noise attenuation characteristics

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Signal integrity management in high-speed digital interfaces
• EMI filtering in compact electronic assemblies with limited clearance

Procurement Notes

Verify that the order quantity accounts for the dual-unit assembly requirement, as two pieces constitute a single functional core. Confirm internal width compatibility with the target flat cable thickness to ensure proper fit within the 0.037-inch height constraint. Check RoHS3 compliance status if required by specific environmental regulations.

Selection Notes

Select this component when retrofitting EMI protection onto pre-assembled flat ribbon cables is necessary. The split design eliminates the need to thread cables through solid cores. Ensure the operating frequency range aligns with the Material 28 impedance profile centered around 100MHz for effective noise reduction.

Part Context

This part belongs to the 28B and 28S series of cable ferrites from Laird-Signal Integrity Products. These components are engineered for signal integrity enhancement in dense electronic environments. The split format distinguishes it from solid cylindrical or rectangular cores, offering unique installation flexibility for ribbon cable geometries.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific split geometry and dimension set.
