28A2005-0A2

Overview

The Laird-Signal Integrity Products 28A2005-0A2 is a hinged snap-on ferrite core designed for cable noise suppression. It features Material 28 composition and provides an impedance of 190 Ohms at 100MHz. The component has a circular shape with a free-hanging installation type. Internal dimensions are 0.197 inches (5.00mm) diameter, while external dimensions measure 0.512 inches wide by 0.461 inches high (13.00mm x 11.70mm). It belongs to the 28A series and complies with RoHS3 standards.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection
• Material 28 composition provides broadband electromagnetic interference suppression
• Free-hanging configuration enables flexible mounting in various spatial constraints

Applications

• Data cable noise reduction
• Power cable filtering
• Audio cable interference mitigation

Procurement Notes

Verify the specific impedance value and physical dimensions against the official manufacturer datasheet before procurement. Confirm that the hinge mechanism is intact and functional upon receipt. Ensure the material designation matches project requirements for frequency response characteristics. Check for compliance with relevant environmental regulations such as RoHS3 status.

Selection Notes

Select this component when a non-invasive solution for cable EMI suppression is required. The hinged design facilitates retrofitting onto installed wiring harnesses. Consider the internal diameter to ensure compatibility with the target cable size. Evaluate the impedance profile at the specific noise frequencies of interest to ensure effective attenuation performance.

Part Context

This part belongs to the 28A series of broad band EMI split/snap-on ferrite cable cores from Laird-Signal Integrity Products. These components are engineered for signal integrity applications where rapid deployment and effective noise cancellation are critical. The series offers various sizes and impedance values to suit different cable diameters and frequency ranges.

Replacement Considerations

Check for direct substitutes within the 28A series with matching internal diameter and similar impedance ratings. Verify hinge compatibility and overall envelope dimensions to ensure fitment in existing assemblies.
