28B0375-3

Overview

The Leader Tech Inc. 28B0375-3 is a solid round ferrite bead core designed for single cable applications. It features a Nickel-Zinc (NiZn) material composition, designated as Material 28. The component has an inner diameter of 4.88 mm and an outer diameter of 9.53 mm, with a length of 19.05 mm. It provides an impedance of 140 Ohms at 100 MHz.

Feature Summary

• Solid round construction for single cable clamping
• Nickel-Zinc material composition for high-frequency performance
• Snap-on installation method

Applications

• Single cable EMI suppression
• High-frequency noise filtering
• Cable harness protection

Procurement Notes

Verify the specific manufacturer designation when sourcing, as LeaderTech products are often distributed by multiple electronics retailers. Confirm that the NiZn material type matches the target frequency range requirements. Ensure the inner diameter specification aligns precisely with the cable bundle or single wire being treated to guarantee proper mechanical fit and magnetic coupling efficiency.

Selection Notes

Select this component when a solid round geometry is required for single conductors rather than split cores. The 4.88 mm inner diameter accommodates cables within this specific size range. Consider the 140 Ohm impedance at 100 MHz for suitability in high-frequency noise reduction scenarios typical of digital signal lines or power cables in electronic assemblies.

Part Context

This part belongs to the LeaderTech family of solid ferrite beads and rings. It utilizes Material 28, a standard Nickel-Zinc formulation optimized for frequencies above 1 MHz. The product line includes various shapes such as toroids and beads, with this specific model focusing on cylindrical geometry for straightforward cable wrapping.
