FX28R1457-4A

Overview

The FX28R1457-4A is a low-profile ferrite cable core manufactured by LeaderTech. It features an integrated adhesive backing for secure attachment to cables or surfaces. The component provides an impedance of 140 Ohms at a test frequency of 100 MHz. Its physical dimensions are 33 mm in length and 0.50 mm in thickness, designed for compact electronic assemblies requiring EMI suppression.

Feature Summary

• Integrated adhesive backing for direct mounting
• Low-profile geometry for space-constrained applications
• Ferrite material construction for high-frequency noise attenuation

Applications

• EMI suppression on flat ribbon cables
• Noise filtering in compact electronic enclosures
• Signal integrity enhancement for high-speed data lines

Procurement Notes

Verify the specific impedance value of 140 Ohms at 100 MHz against your design requirements. Confirm that the low-profile adhesive type matches your assembly process. Ensure the 33 mm length and 0.50 mm thickness fit within your spatial constraints. Check RoHS compliance status through official manufacturer documentation before finalizing procurement.

Selection Notes

Select this part when space is limited due to its thin 0.50 mm profile. Choose it for applications requiring fixed attachment via adhesive rather than snap-fit mechanisms. Consider it for flat cable geometries where standard round cores are unsuitable. Validate that the 140 Ohm impedance aligns with the target noise frequencies in your circuit design.

Part Context

This component belongs to the FX28 series of ferrite cable cores from LeaderTech. It is categorized under EMI/RFI shielding products. The series focuses on providing effective electromagnetic interference suppression for interconnect cables in various electronic devices.

Replacement Considerations

Consult official LeaderTech documentation for verified substitute part numbers. Do not assume generic ferrite cores are compatible due to specific impedance and adhesive differences.
