28R1779-100

Overview

The 28R1779-100 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It belongs to the 28R series and utilizes material grade 28 for broadband EMI filtering. The component exhibits an impedance of 170 Ohms at 100 MHz. Its physical dimensions include an internal slot size of 52.07 mm in width by 1.67 mm in height, with external dimensions of 54.07 mm in width and 3.67 mm in height.

Feature Summary

• Solid construction designed for free-hanging installation on cables or wires.
• Utilizes Material 28 composition to provide effective broadband electromagnetic interference suppression.
• Features a large internal slot capacity suitable for accommodating thicker conductors.

Applications

• Suppression of unintended signals on power cables
• Filtering emissions from signal wires
• Common mode noise reduction on data lines

Procurement Notes

Verify the specific internal slot dimensions against the target cable diameter prior to procurement. Confirm that the solid design aligns with the assembly requirements, as this component is not split or snap-on. Ensure the manufacturer part number matches exactly to avoid compatibility issues with existing designs.

Selection Notes

Select this component when high-capacity cable filtering is required due to its substantial internal slot size. The 170 Ohm impedance at 100 MHz indicates suitability for general broadband noise suppression. Consider the solid form factor if retrofitting onto existing cabling is not necessary and permanent mounting is preferred.

Part Context

This ferrite core is part of Laird's 28R series, which focuses on solid cores for robust EMI mitigation. Unlike split cores, these are installed during the manufacturing or initial cable preparation phase. The series offers various impedance values and material grades to tailor filtering performance to specific frequency ranges.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model were not identified in the provided documentation. Verify electrical impedance and physical slot dimensions when evaluating alternative components from other manufacturers.
