CA28B0937

Overview

The CA28B0937 is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It utilizes material grade 28 and provides an impedance of 117 Ohms at 100 MHz. The component features a circular shape with a free-hanging design. Internal dimensions include a diameter of 10.21 mm (0.402 inches), while the external diameter measures 27.40 mm (1.079 inches). The total length of the unit is 1.291 inches.

Feature Summary

• Hinged snap-on installation mechanism for secure attachment to cables
• Free-hanging configuration allowing flexible positioning on round conductors
• Material grade 28 composition for effective electromagnetic interference suppression

Applications

• Suppression of electromagnetic interference on round cables
• High-frequency noise reduction in electronic assemblies
• EMI filtering for signal and power lines requiring snap-on access

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the snap-on hinge mechanism meets the mechanical retention requirements of the target assembly. Ensure compatibility with the cable diameter range specified by the manufacturer to maintain optimal magnetic coupling and performance.

Selection Notes

Select this component when a reusable, non-destructive mounting solution is required for round cables. The hinged design facilitates rapid installation and removal without cutting or stripping wires. Consider the 117 Ohm impedance at 100 MHz to ensure it aligns with the frequency spectrum of the noise sources present in the application environment.

Part Context

This part belongs to the Leader Tech Inc. ferrite clamp-on core product line. These components are designed for EMI suppression in various electronic systems. The CA28B0937 specifically addresses applications needing easy access to cables for maintenance or modification while providing consistent high-frequency attenuation characteristics.

Replacement Considerations

Direct substitutes may include other snap-on ferrites with similar internal diameters and impedance profiles. Verify that alternative parts maintain the same hinge mechanism and material grade to ensure equivalent performance and mechanical fit in existing designs.
