28B0470-000

Overview

The Laird-Signal Integrity Products 28B0470-000 is a solid, free-hanging ferrite cable core designed for electromagnetic interference suppression. It features an impedance of 211 Ohms at a test frequency of 100 MHz. The component has a cylindrical geometry with an inside diameter of 5.6 mm (0.220 inches), an outside diameter of 12.0 mm (0.472 inches), and an external length of 20.0 mm (0.787 inches). It is constructed from material designated as type 28.

Feature Summary

• Provides high impedance to suppress common-mode noise on cables
• Solid cylindrical design allows easy sliding onto existing wires
• Constructed from type 28 ferrite material for effective broadband attenuation

Applications

• High-power motor control cabinets
• Signal integrity enhancement in electronic assemblies
• Cable noise suppression in industrial equipment

Procurement Notes

Verify the specific impedance requirement of 211 Ohms at 100 MHz against the target application's noise spectrum. Confirm that the 5.6 mm inner diameter accommodates the cable bundle without excessive force or loose fit. Ensure the physical dimensions align with available space constraints in the assembly. Check for RoHS compliance status if required by the end product regulations.

Selection Notes

Select this component when a snap-on ferrite solution is preferred over split cores for permanent installations. The solid construction offers mechanical stability compared to hinged alternatives. Consider the thermal environment, as ferrite performance can vary with temperature. The 20 mm length provides a balance between attenuation effectiveness and spatial footprint.

Part Context

This part belongs to the 28B series of round cable cores from Laird-Signal Integrity Products. These components are engineered for signal integrity applications requiring passive EMI filtering. The series utilizes specific ferrite formulations optimized for different frequency ranges, with this unit targeting higher impedance characteristics at 100 MHz.
