28R0453-200

Overview

The Laird-Signal Integrity Products 28R0453-200 is a solid free-hanging ferrite core designed for electromagnetic interference suppression. It exhibits an impedance of 104 Ohms at a test frequency of 100 MHz. The component features a rectangular cross-section with an internal width of 0.315 inches (8.00 mm) and an internal height of 0.028 inches (0.71 mm). External dimensions measure 0.453 inches in width (11.50 mm) and 0.118 inches in height (3.00 mm).

Feature Summary

• Solid construction provides mechanical stability for flat ribbon cables.
• Free-hanging design allows for easy installation without mounting hardware.
• Ferrite material offers effective high-frequency noise attenuation.

Applications

• Suppression of electromagnetic interference on flat ribbon cables.
• Signal integrity enhancement in digital data transmission lines.
• Noise filtering in computer peripheral connections.

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet to ensure compatibility with target cable assemblies. Confirm that the solid core design meets the mechanical requirements of the application environment. Check RoHS compliance status if restricted substances are a concern for the final product assembly.

Selection Notes

Select this component when a low-profile, non-magnetic clamp solution is required for flat cables. The 104 Ohm impedance at 100 MHz suits general-purpose digital noise suppression. Ensure the cable thickness fits within the 0.028-inch internal height constraint. Consider the free-hanging form factor for applications where space constraints prevent the use of split-core or snap-on alternatives.
