28R0906-000

Overview

The 28R0906-000 is a solid ferrite core manufactured by Laird-Signal Integrity Products. It is designed for use as a free-hanging magnetic core in electromagnetic interference suppression applications. The component features a specific impedance characteristic of 123 Ohms at 100 MHz, providing effective noise attenuation across high-frequency ranges. Its physical dimensions include an inner diameter of 0.827 inches and a width of 0.031 inches, with an outer diameter of 0.984 inches and a height of 0.118 inches. This axial geometry allows for straightforward installation around cables or wires to enhance signal integrity.

Feature Summary

• Solid construction provides durable electromagnetic interference suppression
• Free-hanging design facilitates easy installation around conductors
• Specific impedance profile targets high-frequency noise reduction

Applications

• Cable noise suppression in electronic assemblies
• Electromagnetic interference filtering for signal lines
• Power line noise attenuation in industrial equipment

Procurement Notes

Verify the exact impedance value and physical dimensions against the official datasheet before integration. Confirm that the solid core geometry matches the cable diameter requirements of the target application. Ensure compliance with relevant environmental regulations such as RoHS if applicable to the final product deployment.

Selection Notes

Select this component when a through-hole, free-hanging ferrite solution is required rather than a surface-mount bead. Consider the 123 Ohm impedance at 100 MHz for appropriate frequency targeting. Evaluate the physical size constraints to ensure the 0.827-inch inner diameter accommodates the intended wire or cable bundle without excessive strain.

Part Context

This part belongs to the family of solid ferrite cores offered by Laird-Signal Integrity Products. These components are distinct from chip ferrite beads or snap-on cores, offering a robust solution for bulk cable treatment. The manufacturer specializes in signal integrity products, ensuring consistent material properties for EMI mitigation.
