CA28B1642

Overview

The CA28B1642 is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It features a round cable design with an internal diameter of 7.60 mm (0.299 inches) and an external diameter of 21.30 mm (0.839 inches). The component has a length of 22.5 mm (0.882 inches) and provides an impedance of 100 Ohms at 100 MHz. It is designed for free-hanging installation on cables to suppress electromagnetic interference.

Feature Summary

• Hinged snap-on construction allows for easy installation around existing cables without disconnection
• Round geometry accommodates circular cable profiles effectively
• Free-hanging design enables flexible mounting orientation

Applications

• Suppression of electromagnetic interference on single cables
• High-frequency noise filtering in electronic assemblies
• Cable shielding applications requiring non-invasive attachment

Procurement Notes

Verify the specific impedance frequency rating and physical dimensions against the official Leader Tech datasheet before integration. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributor to ensure alignment with project requirements.

Selection Notes

Select this component when a split-core ferrite is required for retrofitting or assembly where cable termination is not feasible. Ensure the target cable diameter falls within the 7.60 mm internal clearance. Compare impedance characteristics at operating frequencies against alternative materials if higher attenuation is needed.

Part Context

This part belongs to the Leader Tech Ferrishield series of clamp-on ferrite cores. These components are engineered for EMI/RFI suppression in various electronic environments. The CA28B1642 specifically utilizes a material formulation optimized for high-frequency performance, distinguishing it from lower-impedance variants in the same product family.

Replacement Considerations

Direct substitutes include CS28B1642, which shares similar dimensions but may differ in material composition. Verify impedance curves and temperature ratings when cross-referencing with other Leader Tech models or third-party equivalents.
