FC28B1240

Overview

The FC28B1240 is a hinged flat cable ferrite core manufactured by Leader Tech Inc. It provides electromagnetic interference suppression with an impedance of 250 Ohms at 100 MHz. The component features a snap-on design for free-hanging installation without adhesive. Internal dimensions are 25.9 mm in length, 1 mm in height, and 13.2 mm in width. External dimensions measure 45.5 mm in length, 28.6 mm in width, and 13.2 mm in height.

Feature Summary

• Hinged snap-on design allows for easy installation on flat ribbon cables
• Free-hanging configuration eliminates the need for adhesive mounting
• Engineered to suppress high-frequency noise in electronic circuits

Applications

• Suppression of electromagnetic interference in flat ribbon cable assemblies
• Noise filtering in high-speed digital signal transmission lines
• EMI mitigation in computer peripheral interconnects

Procurement Notes

Verify the specific impedance rating of 250 Ohms at 100 MHz against your system requirements. Confirm that the internal cross-section accommodates the target flat cable thickness. Ensure the hinged mechanism integrity is suitable for the intended mechanical environment. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a non-permanent, clip-on solution is preferred over glued ferrites. The flat geometry is optimized for ribbon cables rather than round wires. Compare the 250 Ohm impedance against other series like FC28B0121 (97 Ohm) based on the specific frequency range requiring attenuation. Ensure the physical size fits within the available clearance around the cable path.

Part Context

This part belongs to the Leader Tech FC28B series of cable ferrites. These components are designed for EMI/RFI suppression in electronic equipment. The manufacturer specializes in shielding products for circuit boards and interconnects. This specific model utilizes a hinged construction for convenient application on existing cable runs.

Replacement Considerations

The FA28B1240 is a confirmed substitute with identical electrical characteristics and dimensions. The FC28B0121 serves as a parameter-equivalent alternative but offers lower impedance (97 Ohms). Verify that any replacement maintains the required 250 Ohm impedance at 100 MHz for effective noise suppression.
