SA28B0146

Overview

The SA28B0146 is a hinged ferrite core manufactured by Leader Tech Inc., designed for EMI suppression applications. It features a material composition of grade 28, providing an impedance of 120 ohms at 100 MHz. The component has a rectangular cross-section with dimensions of 32 mm in length and 1.50 mm in internal height. It utilizes a hinged design for easy installation around cables without disconnection.

Feature Summary

• Hinged construction allows for quick installation on existing cable assemblies
• Grade 28 ferrite material provides effective high-frequency noise attenuation
• Flat profile accommodates thin ribbon or flat cables

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise reduction in data transmission lines
• EMI filtering in compact electronic device interconnects

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before procurement. Confirm RoHS compliance status as per current manufacturer specifications. Ensure the hinged mechanism integrity is maintained during handling to prevent damage to the ferrite material or hinge structure.

Selection Notes

Select this component when space constraints require a low-profile ferrite solution for flat cables. The 120-ohm impedance at 100 MHz suits general-purpose EMI suppression. Compare internal height requirements with cable thickness to ensure proper fit. Consider the hinged design for maintenance-friendly installations where cable removal is undesirable.

Part Context

This part belongs to Leader Tech's line of snap-on and hinged ferrite cores. It is categorized under EMI/RFI filters and specifically targets flat cable applications. The product series typically includes various impedance ratings and physical sizes to accommodate different cable geometries and frequency requirements.
