28B0672-0

Overview

The Leader Tech Inc. 28B0672-0 is a solid round cable ferrite core belonging to the 28 material series, designed for EMI suppression on pre-assembled cables. It features a Nickel-Zinc (NiZn) composition with an impedance of 182 Ohms at 100 MHz. The component has an inner diameter of 8.76 mm and an outer diameter of 25.40 mm. Its physical dimensions include a length of 17.07 mm and a height of 8.76 mm. This snap-fit style bead provides effective noise reduction for high-frequency interference in electronic assemblies.

Feature Summary

• Solid round construction for secure press-fit installation onto cables
• Nickel-Zinc material composition optimized for high-frequency noise absorption
• Pre-formed geometry compatible with standard cable diameters

Applications

• Suppression of electromagnetic interference on pre-assembled data cables
• Noise filtering in high-speed digital signal transmission lines
• EMI mitigation in consumer electronics internal wiring

Procurement Notes

Verify the specific impedance value of 182 Ohms at 100 MHz against your design requirements. Confirm that the 8.76 mm inner diameter accommodates the target cable bundle without excessive force or looseness. Ensure the NiZn material characteristics align with the frequency range of the noise sources present in your application environment.

Selection Notes

Select this component when a solid, non-split ferrite bead is required for permanent installation on existing cables. The 28 material series offers a balance of permeability and resistivity suitable for broadband noise suppression. Consider the physical constraints of the assembly space, as the 25.40 mm outer diameter requires adequate clearance around the cable path.

Part Context

This part belongs to Leader Tech's line of solid round ferrite cores, distinct from split-core alternatives that allow post-assembly installation. The 28 material designation indicates a specific magnetic formulation tailored for frequencies above 10 MHz. These components are typically supplied in bulk quantities for automated or manual insertion into manufacturing processes.

Replacement Considerations

Direct substitutes must match the 8.76 mm inner diameter and 182 Ohm impedance at 100 MHz. Verify that alternative materials maintain similar NiZn characteristics for comparable high-frequency performance. Physical length and outer diameter tolerances should be checked to ensure fit within the enclosure.
