28R1101-000

Overview

The 28R1101-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features a rectangular geometry with an inner dimension of 0.903 inches (22.94mm) width and 0.059 inches (1.50mm) height, and an outer dimension of 1.101 inches (27.97mm) width and 0.305 inches (7.75mm) height. The component has a length of 0.577 inches (14.66mm). It provides an impedance of 140 Ohms at 100 MHz and utilizes material composition 28.

Feature Summary

• Provides EMI suppression for flat or ribbon cable assemblies
• Solid construction designed for free-hanging installation
• Rectangular cross-section accommodates specific cable geometries

Applications

• Suppression of common mode EMI on flat cable assemblies
• Noise reduction on ribbon type cable assemblies
• Signal integrity enhancement in electronic interconnects

Procurement Notes

Verify the exact physical dimensions against the official datasheet to ensure compatibility with the target cable assembly. Confirm that the 140 Ohm impedance specification meets the noise suppression requirements for the intended frequency range. Check RoHS compliance status if required by the end product regulations.

Selection Notes

Select this component when dealing with flat or ribbon cables requiring a solid core solution. Ensure the internal dimensions accommodate the cable thickness and width without excessive force. Consider the operating temperature range and material properties for environmental stability during deployment.

Part Context

This part belongs to the Laird-Signal Integrity Products ferrite core family, specifically designed for electromagnetic interference suppression. It serves as a passive component to attenuate high-frequency noise on data and power lines within electronic systems.

Replacement Considerations

Ensure substitute parts match the 140 Ohm impedance at 100 MHz and the rectangular internal dimensions of 22.94mm x 1.50mm. Verify material composition and mounting style compatibility.
