CW28B0642

Overview

The CW28B0642 is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It features a circular shape and utilizes material grade 28 for EMI suppression. The component has an internal diameter of 7.60 mm (0.299 inches) and an outer diameter of 19.81 mm (0.780 inches). Its external length measures 25.30 mm (0.996 inches). The impedance is specified as 100 Ohms at a test frequency of 100 MHz.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing cables without disconnection
• Utilizes high-impedance ferrite material to suppress electromagnetic interference
• Free-hanging configuration provides flexible mounting options on wire bundles

Applications

• Suppression of common mode noise on cable bundles
• EMI reduction in electronic equipment wiring harnesses
• Interference mitigation on communication and data transmission lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before procurement. Confirm that the internal diameter accommodates the target cable bundle size. Ensure compliance with relevant environmental regulations such as RoHS if required by the application specifications.

Selection Notes

Select this component when a reusable, non-destructive installation method is required for cable EMI suppression. The hinged design facilitates maintenance and retrofitting. Consider the impedance characteristics at the target noise frequency to ensure effective attenuation. Verify that the free-hanging form factor fits within the available spatial constraints of the assembly.

Part Context

This part belongs to the Leader Tech ferrite core family, specifically designed for cable bundle applications. It falls under the category of passive EMI/RFI suppressors. The product line includes various shapes and materials to address different electromagnetic compatibility requirements in industrial and commercial electronics.

Replacement Considerations

Check for direct substitutes from the same manufacturer with identical impedance and dimensional specifications. Ensure any replacement maintains the hinged snap-on mechanism for equivalent installation convenience. Verify material grade compatibility to preserve performance characteristics.
