28R1450-100

Overview

The 28R1450-100 is a solid, free-hanging cable ferrite core manufactured by Laird-Signal Integrity Products. It features a flat rectangular geometry with an impedance of 130 Ohms at 100 MHz. The component utilizes Material 28 for high-frequency noise suppression. Internal dimensions are 1.165 inches wide by 0.030 inches high (29.58 mm x 0.75 mm), while external dimensions measure 1.450 inches wide by 0.305 inches high (36.83 mm x 7.75 mm).

Feature Summary

• Solid construction designed for free-hanging installation on cables.
• Flat profile geometry accommodates wide or ribbon-style conductors.
• Material 28 composition provides specific high-frequency attenuation characteristics.

Applications

• Suppression of electromagnetic interference on wide data cables.
• Noise filtering for ribbon cable assemblies in electronic equipment.
• Common mode noise reduction on flat conductor bundles.

Procurement Notes

Verify the specific material grade and impedance tolerance against the official Laird datasheet before integration. Confirm that the internal width of 1.165 inches adequately fits the target cable bundle without excessive strain. Ensure compliance with RoHS3 standards if required by the final product specifications.

Selection Notes

Select this component when a flat, non-cylindrical ferrite solution is required for wide cables. The 130 Ohm impedance at 100 MHz suits general high-frequency noise suppression. Consider the physical clearance provided by the 1.450-inch outer width during mechanical design to ensure proper fit within the enclosure.

Part Context

This part belongs to the 28R series of cable ferrites from Laird-Signal Integrity Products. These components are engineered for signal integrity applications where standard cylindrical cores cannot accommodate the cross-section of the cable. The series offers various sizes to match different conductor widths.

Replacement Considerations

Direct substitutes include other Laird 28R series cores with compatible internal dimensions. Verify that any alternative maintains the 130 Ohm @ 100 MHz impedance profile and Material 28 composition to ensure equivalent noise suppression performance.
