28R0898-200

Overview

The Laird-Signal Integrity Products 28R0898-200 is a solid flat ribbon cable ferrite core designed for electromagnetic interference suppression. It exhibits an impedance of 127 ohms at a test frequency of 100 MHz. The component features an internal slot dimension of 18.7 mm in length, accommodating specific cable geometries. External dimensions measure 22.8 mm in length, 16 mm in width, and 2.8 mm in height. The core material is designated as type 28. It operates within a temperature range of -40°C to +125°C and is supplied in bulk packaging.

Feature Summary

• Solid construction provides structural integrity for free-hanging installation on cables.
• Optimized geometry accommodates flat ribbon cables with specific internal slot dimensions.
• High impedance characteristics at 100 MHz facilitate effective common-mode noise attenuation.

Applications

• Signal integrity protection for flat ribbon cables in electronic assemblies
• Electromagnetic interference suppression in data transmission lines
• Noise filtering for high-frequency signal paths requiring solid core solutions

Procurement Notes

Verify the manufacturer designation, as some sources list Qnity or LSR while others specify Laird-Signal Integrity Products. Confirm the core material grade is 28 and that the impedance specification matches 127 ohms at 100 MHz. Ensure the internal slot dimensions align with the target cable thickness before procurement.

Selection Notes

Select this component when a solid, non-split ferrite core is required for flat ribbon cables. The 18.7 mm internal length must match the cable profile. Consider the 127 ohm impedance value for the specific frequency band of interest. Verify thermal compatibility with the operating environment limits of -40°C to +125°C.

Part Context

This part belongs to the 28 series of ferrite cable cores from Laird-Signal Integrity Products. These components are passive elements used for EMI suppression. The 28 material composition is standard for broadband noise absorption. The product is categorized under flat ribbon cable cores, distinguishing it from round cable clamps or surface-mount beads.
