CA28B0642

Overview

The CA28B0642 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc., designed for suppressing electromagnetic interference on cables. It features an adhesive base and a barrel cable design with a snap-fit mechanism for secure installation. The component utilizes material grade 28, providing an impedance of 100 ohms at 100 MHz. Key physical dimensions include an inner diameter of 7.60 mm (0.30 inches) and an outer diameter of 19.9 mm (0.78 inches). The unit is RoHS compliant and lead-free.

Feature Summary

• Hinged snap-fit design allows for easy installation around existing cables without disconnection
• Integrated adhesive base ensures permanent mounting to surfaces or equipment enclosures
• Barrel shape construction provides uniform magnetic flux distribution around the conductor
• Material grade 28 formulation optimized for high-frequency noise suppression

Applications

• Suppression of common-mode noise on data and power cables in electronic assemblies
• EMI reduction in telecommunications and networking infrastructure equipment
• Noise filtering for automotive wiring harnesses and control modules
• Interference mitigation in industrial automation sensor and actuator lines

Procurement Notes

Verify that the specific order matches the CA28B0642 part number, as Leader Tech offers similar variants like SB28B0642 and TC28B0642 which differ in mounting style or impedance characteristics. Confirm the presence of the adhesive base feature, as some hinged cores are free-hanging. Ensure compliance requirements such as RoHS status align with project specifications before finalizing procurement.

Selection Notes

Select this component when a permanent, non-removable ferrite solution is required due to its adhesive backing. Choose based on the 100 ohm impedance requirement at 100 MHz for the target noise spectrum. Ensure the cable diameter fits within the 7.60 mm inner diameter clearance. Consider the mechanical constraints of the adhesive application surface for proper bonding strength.

Part Context

This component belongs to the Leader Tech ferrite clamp-on core family, specifically the CA series characterized by adhesive mounting options. It complements other hinged cores like the SB and TC series, offering a distinct installation method suitable for applications where mechanical retention via screws or straps is not feasible or desired.
