28B0773-050

Overview

The Laird-Signal Integrity Products 28B0773-050 is a solid, free-hanging cable ferrite core designed for electromagnetic interference suppression. It exhibits an impedance of 141 Ohms at a test frequency of 100 MHz and utilizes Material 28. The component features a rectangular cross-section with internal dimensions of 11.64 mm width by 5.10 mm height, and external dimensions of 19.64 mm width by 13.10 mm height. Its total length measures 12.70 mm. This part is RoHS compliant and operates without radiation hardening.

Feature Summary

• Solid construction provides structural integrity for cable management applications
• Material 28 composition offers specific high-frequency attenuation characteristics
• Free-hanging design allows for easy installation on existing wiring harnesses

Applications

• Electromagnetic interference suppression on signal cables
• Noise filtering in electronic equipment wiring
• Cable assembly EMI mitigation

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the physical inner dimensions accommodate the target cable diameter without excessive force or loose fit. Ensure compliance requirements match project specifications, particularly regarding RoHS status and absence of radiation hardening.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. The rectangular geometry suits flat or bundled cable arrangements better than circular cores. Consider the 141 Ohm impedance profile at 100 MHz to ensure adequate noise suppression for the specific frequency spectrum of the application.
