FA28B3012

Overview

The FA28B3012 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc., designed for flat ribbon cables. It utilizes Material 28 to provide electromagnetic interference suppression with an impedance of 286 Ohms at 100 MHz. The component features a snap-on design for easy installation without cable disconnection. Physical dimensions include an internal length of 64.5 mm and an internal height of 1.5 mm, accommodating specific flat cable profiles. The external dimensions are 82.8 mm in length, 33.3 mm in width, and 17 mm in height. It is supplied in bulk packaging.

Feature Summary

• Hinged snap-on design allows for installation on existing flat ribbon cables without disconnecting the wiring.
• Material 28 composition provides high impedance characteristics for effective EMI noise suppression.
• Fully enclosed structure protects the magnetic core and ensures consistent performance around the cable.

Applications

• Suppression of electromagnetic interference on flat ribbon cables in computer peripherals
• Noise reduction on data transmission lines within electronic equipment chassis
• EMI filtering for internal cabling in industrial control systems

Procurement Notes

Verify that the target flat ribbon cable thickness does not exceed the 1.5 mm internal height specification to ensure proper fit. Confirm that the required impedance level aligns with the Material 28 characteristic of 286 Ohms at 100 MHz. Check for any specific RoHS compliance requirements if operating in regulated environments. Ensure the hinged mechanism is accessible for installation during the assembly process.

Selection Notes

Select this part when working with flat ribbon cables requiring snap-on EMI solutions. Material 28 is suitable for frequencies around 100 MHz where moderate to high attenuation is needed. Compare internal dimensions against the specific cable bundle size to avoid over-tightening or loose fitting. Consider the physical space constraints given the external length of 82.8 mm and height of 17 mm.

Part Context

This component belongs to the FerriShield series of cable ferrites from Leader Tech Inc. It is categorized under Ferrite Clamp On Cores specifically designed for flat cables. The product line focuses on providing convenient, non-destructive EMI mitigation options for various electronic interconnects.

Replacement Considerations

RC28B3012 is a similar fully enclosed ferrite clamp from Leader Tech using Material 28, but it lacks the hinged design. Verify if the non-hinged RC28B3012 can be installed on the existing cable assembly; otherwise, the hinged FA28B3012 is required for retrofit applications.
