28B1020-100

Overview

The 28B1020-100 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It utilizes Material 28 to provide electromagnetic interference suppression with an impedance of 276 Ohms at 100 MHz. The component features a circular design with an inner diameter of 12.83 mm and an outer diameter of 25.91 mm. Its physical length measures 28.58 mm, allowing it to accommodate cables of significant thickness for effective noise filtering in power and signal lines.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Utilizes Material 28 formulation for specific frequency attenuation characteristics
• Circular geometry accommodates large diameter conductors

Applications

• Cable assembly EMI suppression
• Power line noise filtering
• Signal line interference reduction

Procurement Notes

Verify the exact material grade and impedance specifications against the official Laird datasheet before integration. Confirm that the inner diameter of 12.83 mm matches the target cable bundle size to ensure proper fit. Check RoHS compliance status and export control classifications such as ECCN EAR99 for regulatory adherence during procurement.

Selection Notes

Select this component when high current capacity or large cable diameters require a through-hole style ferrite solution. The Material 28 composition offers distinct performance compared to other Laird formulations. Ensure the application environment supports free-hanging mounting rather than surface-mount constraints.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. It serves as a passive component for mitigating common-mode noise in electronic systems. The product is categorized under cable ferrites and is distinct from chip bead or core-and-clip variants.
