28R0898-100

Overview

The 28R0898-100 is a solid ferrite core designed for flat ribbon cables, manufactured by Laird-Signal Integrity Products under the 28R series. It provides an impedance of 110 Ohms at a test frequency of 100 MHz. The component features a rectangular cross-section with internal dimensions of 18.70mm x 0.70mm and external dimensions of 22.80mm x 2.80mm. The total length is 12.00mm. Constructed from material grade 28, it supports free-hanging installation and complies with RoHS3 standards.

Feature Summary

• Solid construction optimized for flat ribbon cable suppression
• High impedance performance at 100 MHz for EMI reduction
• Free-hanging mounting design for flexible integration

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Signal integrity enhancement in data transmission lines
• Noise filtering in electronic assemblies requiring free-hanging cores

Procurement Notes

Verify the specific manufacturer part number against official Laird documentation to ensure authenticity. Confirm that the required impedance value of 110 Ohms at 100 MHz aligns with the system's noise profile. Check for RoHS3 compliance requirements if operating in regulated regions. Ensure physical dimensions fit the available space for flat cable routing.

Selection Notes

Select this component when managing flat ribbon cables rather than round wires due to its rectangular geometry. The 110 Ohm impedance rating suits general-purpose high-frequency noise suppression. Consider the 12mm length and slot size to ensure adequate cable coverage without excessive bulk. Verify compatibility with the target cable thickness relative to the 0.70mm internal height.

Part Context

This component belongs to the 28R series of ferrite cable cores, which are engineered specifically for suppressing electromagnetic interference on flat conductors. Unlike cylindrical cores, these solid rectangular units provide uniform magnetic coupling across the width of ribbon cables, making them suitable for parallel signal lines where consistent attenuation is required.

Replacement Considerations

Cross-reference with other 28R series parts such as 28R0898-200 for higher impedance needs. Ensure substitute components maintain the same 110 Ohm @ 100 MHz specification and compatible physical dimensions for flat cable applications.
