FC28B0121

Overview

The FC28B0121 is a hinged flat cable ferrite core manufactured by Leader Tech Inc. It features an internal dimension of 25.7 mm width and 1.5 mm height, with external dimensions of 45.5 mm length, 19.1 mm width, and 13.2 mm height. The component provides an impedance of 97 Ohms at 100 MHz and utilizes Material 28. It is designed for free-hanging installation without adhesive backing.

Feature Summary

• Hinged snap-on design allows for easy attachment to existing flat ribbon cables without disconnection.
• Material 28 composition provides specific high-frequency noise suppression characteristics.
• Free-hanging configuration enables flexible mounting on various cable assemblies.

Applications

• Suppression of electromagnetic interference in flat ribbon cable assemblies
• Noise filtering in portable electronic devices
• EMI mitigation in power supply circuits

Procurement Notes

Verify the exact material grade and impedance specifications against the official manufacturer datasheet before integration. Confirm that the hinged design accommodates the specific thickness of the target flat cable assembly. Ensure compliance with relevant environmental regulations such as RoHS requirements for the intended market.

Selection Notes

Select this component when a non-destructive, reusable clamping solution is required for flat cables. The 97 Ohm impedance at 100 MHz suits applications targeting common-mode noise in that frequency range. Compare internal dimensions against the cable bundle size to ensure a secure fit within the hinge mechanism.

Part Context

This part belongs to the Leader Tech Inc. FC series of clamp-on ferrites. It is functionally similar to the FA28B0121 but distinguished by its specific dimensional profile and lack of adhesive backing. It serves as a passive EMI suppression element within broader cable management systems.

Replacement Considerations

Public documentation identifies the FA28B0121 as a parameter-equivalent substitute. Verify that the alternative matches the required internal dimensions and impedance characteristics for the specific application.
