28R1103-000

Overview

The 28R1103-000 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features a flat design constructed from Material 28, providing an impedance of 230 Ohms at 100 MHz. The component has an inner dimension of 0.906 inches wide by 0.043 inches high (23.00mm x 1.10mm) and an outer dimension of 1.102 inches wide by 0.240 inches high (28.00mm x 6.10mm). Its length measures 1.063 inches (27.00mm).

Feature Summary

• Solid construction designed for free-hanging installation on cables.
• Utilizes Material 28 composition for specific frequency attenuation.
• Flat profile geometry accommodates wiring harnesses.

Applications

• Cable and wiring EMI suppression
• Signal integrity management in electronic assemblies

Procurement Notes

Verify the exact part number against manufacturer documentation to ensure compliance with current specifications. Confirm that the Material 28 composition aligns with project requirements. Check RoHS3 status if environmental regulations apply. Ensure physical dimensions match available space constraints before procurement.

Selection Notes

Select this component when a non-soldered, removable ferrite solution is required for cable management. The free-hanging design allows for easy installation without PCB footprint allocation. Consider the 230 Ohm impedance characteristic for target noise frequencies. Evaluate the physical size relative to cable diameter and enclosure clearance.

Part Context

This component belongs to the Laird-Signal Integrity Products ferrite core series. It serves as a passive electromagnetic interference filter. The product is distinct from surface-mount or through-hole bead variants due to its bulk form factor. It supports signal integrity efforts in complex wiring environments.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify dimensional compatibility and impedance characteristics before swapping components. Ensure material composition matches original design intent.
