28B0369-000

Overview

The 28B0369-000 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 140 Ohms at 100 MHz and utilizes material composition 28. The component features a circular design with an inner diameter of 5.97 mm (0.235 inches), an outer diameter of 10.01 mm (0.394 inches), and a length of 6.17 mm (0.243 inches). It operates within a temperature range of -55°C to +125°C and is RoHS3 compliant.

Feature Summary

• Solid round construction designed for routing cables or leads through the center aperture.
• Provides high impedance noise suppression for EMI/RFI reduction on signal lines.
• Utilizes Material 28 formulation for effective frequency-dependent attenuation.

Applications

• Cable and lead noise suppression in electronic assemblies
• Signal integrity improvement for high-frequency circuits
• EMI/RFI filtering for power and data transmission lines

Procurement Notes

Verify the specific impedance value and material grade against the official datasheet before integration. Confirm that the physical dimensions match the available cable or wire gauge for proper installation. Ensure compliance with project-specific environmental regulations such as RoHS3 status.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. Consider the 140 Ohm impedance at 100 MHz to ensure adequate attenuation for the target noise frequencies. Evaluate the 5.97 mm inner diameter to verify compatibility with the conductor size.

Part Context

This part belongs to the 28B series of solid ferrite cores from Laird-Signal Integrity Products. These components are engineered for general-purpose electromagnetic interference suppression. The solid design distinguishes it from split-core alternatives, making it suitable for applications where the cable can be threaded through during assembly.
