28R1779-000

Overview

The Laird-Signal Integrity Products 28R1779-000 is a solid free-hanging ferrite core designed for electromagnetic interference (EMI) suppression. It exhibits an impedance of 298 Ohms at 100 MHz. The component features a rectangular geometry with an internal slot width of 52.07 mm and a height of 1.68 mm. The outer dimensions are 2.500 inches in width and 0.500 inches in height. This solid core design provides broadband noise attenuation for cables passing through the aperture.

Feature Summary

• Solid construction for robust EMI/RFI noise suppression on flat or round cables
• High impedance characteristic effective for broadband signal integrity improvement
• Free-hanging installation method suitable for various cable configurations

Applications

• Suppression of unintended signals on flat ribbon cables
• Noise filtering on power and data transmission lines
• Broadband EMI shielding in electronic assemblies

Procurement Notes

Verify the specific part number suffix, as variants such as 28R1779-100 may exist with different dimensional or material specifications. Confirm RoHS compliance status and ensure the internal slot dimensions match the target cable thickness to guarantee proper fit and performance. Cross-reference official datasheets for accurate mechanical tolerances before integration.

Selection Notes

Select this component when high impedance at 100 MHz is required for broadband noise reduction. Ensure the cable diameter fits within the 52.07 mm internal slot. Consider the solid core design for applications requiring durable, non-split magnetic materials that do not require snap-on mechanisms.

Part Context

This component belongs to the Laird-Signal Integrity Products cable ferrite series, specifically engineered for EMI suppression. It complements split-core options by offering a permanent solid magnetic path. The product line focuses on enhancing signal integrity across various industrial and commercial electronic systems.
