28R2170-000

Overview

The 28R2170-000 is a solid flat ribbon cable ferrite core manufactured by Laird-Signal Integrity Products. It belongs to the 28R series and utilizes Material 28 for EMI suppression. The component provides an impedance of 280 Ohms at 100 MHz. Its physical dimensions include an inner dimension of 43.69 mm width by 1.27 mm height, and an outer dimension of 55.12 mm width by 12.7 mm height.

Feature Summary

• Solid design suitable for free-hanging installation on cables
• Optimized for high-frequency electromagnetic interference suppression
• Flat geometry engineered specifically for ribbon cable applications

Applications

• Suppression of noise on flat ribbon cables
• EMI filtering in data transmission lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the inner dimensions match the target ribbon cable thickness and width precisely. Ensure the solid construction meets the mechanical requirements of the assembly environment.

Selection Notes

Select this component when dealing with wide ribbon cables requiring significant low-profile suppression. The Material 28 composition offers specific frequency characteristics distinct from other series. Compare the 280 Ohm impedance requirement against system noise spectra to ensure effective attenuation without signal degradation.

Part Context

This part is part of the 28R series of flat cable cores. It complements circular and snap-on ferrite options by addressing the unique geometry of ribbon cables. The solid construction distinguishes it from split-core alternatives, providing a permanent magnetic path for noise reduction.

Replacement Considerations

Check the 28R2170-100 variant which shares similar dimensions but offers 170 Ohms impedance at 100 MHz. Verify if the lower impedance meets the specific EMI suppression requirements of the application.
