28B0825-000

Overview

The 28B0825-000 is a broadband EMI cylindrical ferrite cable core manufactured by Laird-Signal Integrity Products. It features a solid design with an inner diameter of 13.21mm, an outer diameter of 20.95mm, and a length of 6.35mm. The component provides an impedance of 79 Ohms at 100MHz and utilizes material grade 28 for effective noise suppression.

Feature Summary

• Solid molded construction for durable broadband EMI filtering
• Free hanging installation type suitable for loose cable wrapping
• Cylindrical geometry designed to accommodate larger cable bundles

Applications

• Broadband electromagnetic interference suppression on cables
• Signal integrity enhancement in electronic assemblies
• Noise reduction for power and signal lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the inner diameter accommodates the target cable bundle without excessive force. Ensure compliance with RoHS3 standards as indicated in manufacturer documentation.

Selection Notes

Select this component when broadband attenuation is required for cables exceeding standard ferrite sizes. The 13.21mm inner diameter allows for multi-conductor or thick single conductors. Material 28 offers high permeability for effective low-frequency noise absorption.

Part Context

This part belongs to the 28B series of round cylindrical ferrite cores. These components are engineered for general-purpose EMI suppression where surface mount beads are unsuitable due to cable size constraints. The series offers various diameters to match different cable profiles.

Replacement Considerations

Substitute parts must match the 13.21mm inner diameter and 79 Ohm impedance at 100MHz. Verify that alternative materials provide comparable permeability and saturation characteristics for equivalent noise suppression performance.
