28B0631-100

Overview

The Laird-Signal Integrity Products part number 28B0631-100 is a solid core ferrite suppressor designed for round cable applications. It provides an impedance of 243 ohms at 100 MHz and utilizes material composition 28. The component features a cylindrical geometry with an inner diameter of 9.25 mm, an outer diameter of 16.00 mm, and a length of 27.99 mm. This free-hanging design allows for easy installation onto existing cables without requiring soldering or complex mounting hardware.

Feature Summary

• Solid core construction for robust electromagnetic interference suppression
• Free-hanging design suitable for round cable wrapping
• Material 28 formulation optimized for high-frequency noise attenuation

Applications

• Suppression of electromagnetic interference on round cables
• High-frequency noise filtering in signal integrity circuits
• Cable assembly EMI mitigation

Procurement Notes

Verify the specific impedance tolerance and material grade against the official datasheet before integration. Confirm that the physical dimensions align with available cable diameters to ensure proper fit. Check for RoHS compliance status if required by project specifications. Ensure the supplier provides authentic components from Laird-Signal Integrity Products to guarantee performance consistency.

Selection Notes

Select this component when a non-solderable, wrap-around ferrite solution is required for round cables. The 243 ohm impedance at 100 MHz indicates suitability for specific high-frequency noise profiles. Consider the 9.25 mm inner diameter constraint to match target cable sizes. Material 28 selection should be validated against the specific frequency spectrum of the noise being suppressed.

Part Context

This component belongs to the 28B series of cable ferrites manufactured by Laird-Signal Integrity Products. These parts are distinct from surface-mount ferrite beads, offering a mechanical solution for cable-based noise reduction. The 28B series typically utilizes specific ferrite materials tailored for broad-spectrum or targeted frequency suppression in industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 243 ohm impedance at 100 MHz, Material 28 composition, and identical physical dimensions (9.25 mm ID, 16.00 mm OD). Verify compatibility with existing cable diameters and environmental requirements.
