CF28B1984

Overview

The CF28B1984 is a hinged ferrite core manufactured by Leader Tech Inc., designed for cable applications. It features a snap-on installation type with a button base. The component has an inner diameter of 13.30 mm and an outer diameter of 31.00 mm, with a length of 31.00 mm (1.217 inches). It exhibits an impedance of 62 Ohms at 100 MHz. The product is classified as a free-hanging ferrite core and is packaged in bulk quantities.

Feature Summary

• Hinged design allows for easy installation around existing cables without disconnection
• Snap-on mechanism with button base ensures secure retention on the cable
• Free-hanging configuration provides flexibility in mounting orientation

Applications

• Electromagnetic interference suppression on single cables
• High-frequency noise filtering in electronic assemblies
• Cable harness protection against radiated emissions

Procurement Notes

Verify the specific impedance value and dimensional tolerances against the official Leader Tech datasheet before integration. Confirm that the hinged construction meets the mechanical requirements for the intended cable diameter. Ensure compliance with relevant environmental regulations such as RoHS if applicable to the final product deployment.

Selection Notes

Select this component when a non-intrusive solution for adding ferrite suppression to existing cabling is required. The hinged design eliminates the need to disconnect or route cables through solid cores. Consider the 62 Ohm impedance characteristic for effectiveness at high frequencies around 100 MHz. Verify that the 13.30 mm inner diameter accommodates the target cable size with appropriate clearance.

Part Context

This part belongs to the Leader Tech ferrite clamp-on core family, specifically engineered for cable-based EMI mitigation. Unlike split-core variants that require assembly, the hinged design offers a pre-formed magnetic path. It serves as a passive component to attenuate common-mode noise on conductors, complementing other shielding strategies in electronic systems.
