28R0453-300

Overview

The 28R0453-300 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 160 Ohms at 100 MHz. The component features an inner diameter of 0.315 inches (8.00 mm) width by 0.028 inches (0.70 mm) height, and an outer diameter of 0.453 inches (11.50 mm) width by 0.118 inches (3.00 mm) height.

Feature Summary

• Solid construction designed for cable noise suppression
• Free-hanging form factor for easy installation

Applications

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

Procurement Notes

Verify the specific impedance rating and physical dimensions against the target cable diameter before procurement. Confirm that the solid core design aligns with the assembly requirements, as opposed to hinged or split-core alternatives. Ensure compatibility with environmental conditions and regulatory standards such as RoHS3 compliance.

Selection Notes

Select this component when a fixed, non-split ferrite core is required for cables with a cross-section matching the 8.00 mm x 0.70 mm inner opening. Consider the 160 Ohm impedance at 100 MHz for the intended frequency range. Evaluate if the free-hanging style fits within the mechanical constraints of the final product enclosure compared to snap-on variants.

Part Context

This part belongs to the Laird-Signal Integrity Products ferrite core lineup, specifically categorized under cable ferrites. It serves as a passive component for electromagnetic interference reduction. The model number indicates specific physical and electrical characteristics distinct from other series like the 28A or MI/HZ chip bead families.
