28S2023-0M0

Overview

The 28S2023-0M0 is a split core ferrite component manufactured by Laird-Signal Integrity Products, designed for electromagnetic interference (EMI) suppression. It features a clip-together assembly mechanism and operates with an impedance of 250 ohms at the test frequency. The unit is constructed as a free-hanging core intended for use with ribbon and flex cables to provide differential and common mode noise reduction.

Feature Summary

• Split core design allows installation on existing cables without disconnection
• Clip together assembly mechanism simplifies handling and placement
• Provides effective EMI suppression for both differential and common mode signals

Applications

• Suppression on ribbon cables
• Noise filtering on flex cables
• Common mode EMI mitigation in signal lines

Procurement Notes

Verify that the specific application requires a split core rather than a solid clamp-on type. Confirm cable dimensions fit within the core aperture before ordering. Check RoHS status requirements as documentation indicates non-compliance with standard RoHS norms depending on the revision date. Ensure the clip mechanism integrity is suitable for the target environment.

Selection Notes

Select this part when retrofitting or assembling cables where cutting is not feasible. The 250 ohm impedance rating targets specific high-frequency noise profiles. Consider the physical size constraints relative to the cable bundle diameter. Evaluate if the free-hanging mounting style meets the mechanical stability needs of the final assembly compared to adhesive options.

Part Context

This component belongs to the cable ferrites category from Laird-Signal Integrity Products. It serves as a passive filter element distinct from surface mount beads. The product line focuses on providing flexible shielding solutions for various interconnect types, specifically addressing noise issues in data and power transmission lines through magnetic absorption.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing cable diameters if sourcing alternatives. Ensure any replacement maintains the required 250 ohm impedance characteristic at the operating frequency.
