28B2400-000

Overview

The 28B2400-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features an inner diameter of 1.400 inches (35.56mm) and an outer diameter of 2.400 inches (60.96mm). The component has a length of 0.500 inches (12.70mm) and provides an impedance of 135 Ohms at 100 MHz. Designed for cable shielding and signal filtering, it operates without mounting hardware.

Feature Summary

• Solid cylindrical construction for direct cable installation
• Provides high-frequency electromagnetic interference suppression
• Free-hanging design eliminates need for additional fixtures

Applications

• Cable shielding applications
• Signal filtering on power or data lines
• Isolation of high-frequency noise on conductors

Procurement Notes

Verify the specific impedance requirement of 135 Ohms at 100 MHz against circuit specifications. Confirm that the physical dimensions, particularly the 1.400-inch inner diameter, accommodate the target cable bundle size. Ensure the application does not require a mounted configuration, as this part is designed for free-hanging use only.

Selection Notes

Select this component when a large-diameter cable requires broadband noise attenuation without mechanical constraints. The solid core design suits environments where space allows for unsecured placement. Compare the 135 Ohm impedance value with alternative cores to ensure adequate attenuation at the target frequency range for the specific EMI profile.

Part Context

This ferrite core belongs to Laird-Signal Integrity Products' line of passive components for electromagnetic interference management. Unlike surface-mount beads, this bulk core addresses high-current or multi-conductor cable scenarios. It complements other Laird filtering solutions by providing a scalable, non-contact method for noise reduction in industrial and commercial cabling systems.

Replacement Considerations
