ET28B3000

Overview

The ET28B3000 is a hinged ferrite core manufactured by Leader Tech Inc., designed for flat ribbon cable applications. It features a snap-on installation mechanism and operates with an impedance of 370 Ohms at 100MHz. The component measures 64.5mm in length and 1.5mm in height, accommodating a maximum internal diameter of 0.060 inches.

Feature Summary

• Hinged snap-on design for rapid installation on flat cables
• High impedance performance at 100MHz for effective EMI suppression
• Low-profile geometry suitable for constrained spaces

Applications

• Flat ribbon cable EMI suppression
• Data bus line noise reduction
• Peripheral interface cable shielding

Procurement Notes

Verify the specific impedance rating and physical dimensions against the official datasheet to ensure compatibility with target cable widths. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributor before finalizing procurement orders.

Selection Notes

Select this component when a reusable, snap-on ferrite solution is required for flat cables. The hinged design facilitates maintenance and retrofitting without cutting wires. Ensure the cable thickness does not exceed the 1.5mm internal height specification for proper closure.

Part Context

This part belongs to the LeaderTech Ferrishield series of EMI suppression components. It serves as a passive filter element within electronic assemblies, specifically targeting high-frequency noise on parallel data lines and communication buses where compact form factors are critical.

Replacement Considerations

Cross-reference with other hinged ferrite cores from LeaderTech offering similar 370 Ohm impedance at 100MHz. Verify that substitute parts match the 64.5mm length and 1.5mm height constraints to maintain mechanical fit.
