28R0756-000

Overview

The Laird-Signal Integrity Products 28R0756-000 is a solid ferrite cable core designed for electromagnetic interference suppression. It exhibits an impedance of 107 Ohms at a test frequency of 100 MHz. The component features a rectangular geometry with an inner slot dimension of 15.00 mm width by 1.15 mm height, accommodating flat ribbon cables. External dimensions measure 19.20 mm in width and 5.35 mm in height. Constructed from material grade 28, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Solid construction provides structural integrity for free-hanging installation on cables.
• Material grade 28 formulation ensures effective high-frequency noise attenuation.
• Rectangular slot design specifically accommodates flat ribbon cable geometries.

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Signal integrity enhancement in electronic assemblies
• Common mode noise reduction in data transmission lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the inner slot size matches the target cable thickness. Ensure the operating temperature range aligns with the environmental requirements of the final assembly. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when flat ribbon cables require EMI filtering. The 107 Ohm impedance at 100 MHz suits general-purpose noise suppression. The solid design allows for easy manual or automated placement. Consider the physical footprint constraints relative to the available space around the cable routing path.

Part Context

This part belongs to the 28R series of ferrite cores from Laird-Signal Integrity Products. The series utilizes material grade 28 for consistent magnetic properties. These components are engineered for signal integrity applications requiring reliable noise attenuation without adding significant mass or volume to the cable assembly.

Replacement Considerations

Substitute parts must match the 107 Ohm impedance at 100 MHz and the 15mm x 1.15mm inner slot dimensions. Verify compatibility with flat ribbon cable profiles. Ensure the replacement maintains the same material grade and temperature rating for equivalent performance.
