28R0756-200

Overview

The Laird-Signal Integrity Products 28R0756-200 is a solid ferrite cable core designed for flat ribbon cables. It provides an impedance of 140 Ohms at a test frequency of 100 MHz. The component features a slot geometry with internal dimensions of 15.00 mm width by 1.15 mm height and external dimensions of 19.2 mm length, 16 mm width, and 5.35 mm height. Constructed from material grade 28, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Solid construction designed specifically for flat ribbon cable applications
• Provides high impedance attenuation at 100 MHz to suppress electromagnetic interference
• Free-hanging mounting style allows for easy installation on existing cable assemblies

Applications

• Suppression of common mode noise in flat ribbon cable assemblies
• Signal integrity enhancement in high-speed digital data lines
• Electromagnetic interference filtering in computer peripheral connections

Procurement Notes

Verify the specific impedance value of 140 Ohms at 100 MHz against your design requirements. Confirm that the internal slot dimensions of 15.00 mm x 1.15 mm accommodate the target flat ribbon cable thickness and width. Ensure the operating temperature range of -40°C to +125°C meets environmental conditions. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when dealing with flat ribbon cables rather than round wires due to its rectangular slot profile. The 140 Ohm impedance level is suitable for general-purpose EMI suppression in digital circuits. Consider the physical size constraints as the external length is 19.2 mm. Material grade 28 offers stable performance across the specified temperature range.

Part Context

This part belongs to the 28R series of ferrite cores manufactured by Laird-Signal Integrity Products. The series focuses on signal integrity solutions for electronic interconnects. The 28R designation indicates a specific material composition optimized for broadband noise suppression. These components are widely used in consumer electronics and industrial equipment to meet regulatory emissions standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite cores based on matching impedance curves, slot dimensions, and material properties before substitution.
