28B0562-100

Overview

The 28B0562-100 is a solid, free-hanging cable ferrite core manufactured by Laird-Signal Integrity Products. It utilizes material 28 to provide electromagnetic interference suppression for cables and wires. The component features an inner diameter of 6.35 mm (0.250 inches) and an outer diameter of 14.27 mm (0.562 inches). Its physical length is 13.46 mm (0.530 inches). At a frequency of 100 MHz, the device exhibits an impedance of 184 ohms. It is designed for surface mounting applications involving wire wrapping.

Feature Summary

• Solid cylindrical design for easy installation on existing cables
• Utilizes Material 28 composition for effective high-frequency noise attenuation
• Free-hanging configuration allows flexible placement along wire harnesses

Applications

• Suppression of unintended signals on communication cables
• Reduction of radiated emissions from power supply wiring
• Common mode filtering in electronic equipment cabling

Procurement Notes

Verify the specific impedance requirement at 100 MHz against system noise profiles before procurement. Confirm that the 6.35 mm inner diameter accommodates the target cable bundle without excessive strain. Ensure compatibility with Material 28 characteristics for the intended frequency range. Check for RoHS3 compliance status if required by assembly specifications.

Selection Notes

Select this component when a solid, non-split ferrite core is preferred over split designs for permanent installations. Consider the 184 ohm impedance value relative to the noise spectrum requiring suppression. Evaluate the physical dimensions to ensure adequate clearance within the enclosure. Compare Material 28 performance against other compositions if lower frequency attenuation is needed.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. The series offers various sizes and impedance values using Material 28. These components are distinct from chip ferrite beads or toroidal cores used on PCBs. They are specifically engineered for post-assembly cable treatment rather than integrated circuit protection.
