FA28B3000

Overview

The FA28B3000 is a hinged flat cable ferrite core manufactured by LeaderTech Inc. It features a snap-on design for easy installation on ribbon cables. The component has an internal length of 64.5 mm and an internal height of 1.5 mm. It provides an impedance of 370 Ohms at a test frequency of 100 MHz. The external dimensions are 64.50 mm in width and 1.50 mm in height. This part is designed for EMI suppression applications.

Feature Summary

• Hinged snap-on design allows for quick installation and removal from flat ribbon cables without disconnecting wires.
• Provides high impedance to suppress electromagnetic interference (EMI) on data lines.
• Solid construction suitable for securing against noise in electronic assemblies.

Applications

• Suppression of EMI on parallel ribbon cables in computer peripherals
• Noise reduction on flat cable interfaces in industrial control systems
• EMI filtering for communication cables in electronic equipment

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before procurement, as specifications may vary by revision. Confirm RoHS compliance status with the manufacturer or authorized distributor. Ensure the internal height matches the target cable thickness for proper fit. Check for any specific adhesive requirements if additional fixation is needed beyond the hinge mechanism.

Selection Notes

Select this component when a non-invasive EMI solution for flat ribbon cables is required. The hinged design facilitates maintenance and retrofitting. Consider the 370 Ohm impedance at 100 MHz for compatibility with the noise frequencies present in the application. Ensure the cable width fits within the core's internal dimensions to maximize attenuation effectiveness.

Part Context

This part belongs to the LeaderTech ferrite clamp-on core family, specifically designed for flat ribbon cables. These components are used to mitigate common-mode noise in high-speed digital circuits. The FA series typically denotes specific material compositions optimized for particular frequency ranges.

Replacement Considerations

FA28B1240: Similar flat cable ferrite but with different dimensions and potentially different impedance characteristics. Verify internal height and length compatibility. SA28B3500: Another flat cable option with adhesive backing; check if hinged vs. adhesive installation suits the assembly needs.
