28B2000-3

Overview

The Leader Tech Inc. 28B2000-3 is a solid round ferrite bead designed for cable tie mounting. It utilizes Material 28 composition to provide high impedance characteristics, specifically rated at 381 Ohms at 100 MHz. The component features an inner diameter of 1.000 inch (25.40 mm) and an overall length of 2.000 inches (50.80 mm). This passive EMI suppression device is classified as a Ferrite Toroid or Solid Round Ferrite Bead, intended for direct integration into cable bundles to mitigate electromagnetic interference.

Feature Summary

• Solid round construction for secure cable tie attachment
• Material 28 composition for specific frequency attenuation
• High impedance rating of 381 Ohms at 100 MHz

Applications

• Cable bundle EMI suppression
• Electromagnetic interference mitigation in wiring harnesses
• Passive filtering for signal cables

Procurement Notes

Verify the exact physical dimensions and material grade against the official manufacturer datasheet before integration. Confirm that the 381 Ohm impedance specification at 100 MHz aligns with the target noise frequencies. Ensure compatibility with existing cable tie mounting methods and check for any RoHS compliance documentation required by the end application standards.

Selection Notes

Select this component when a solid, non-split ferrite design is required for permanent cable installation. The Material 28 formulation offers distinct magnetic properties suitable for specific broadband noise suppression needs. Consider the 25.40 mm inner diameter to ensure it accommodates the target cable bundle size without excessive force or loose fit during the tying process.

Part Context

This part belongs to the Leader Tech Inc. ferrite core family, specifically within the solid round bead category. It serves as a passive component for EMI/RFI suppression, differing from snap-on cores which allow for retrofitting. The product status is listed as active, indicating ongoing manufacturing support and availability for new designs requiring fixed-diameter ferrite solutions.
