28A3851-0A2

Overview

The Laird-Signal Integrity Products 28A3851-0A2 is a hinged, snap-on ferrite core designed for cable EMI suppression. It features Material 28 composition and provides an impedance of 260 Ohms at 100 MHz. The component has a circular shape with a free-hanging installation type. Internal dimensions are 0.512 inches (13.00 mm) diameter, while external dimensions measure 1.181 inches (30.00 mm) diameter by 1.327 inches (33.70 mm) length. It complies with RoHS3 standards.

Feature Summary

• Hinged snap-on design allows for easy installation on existing cables without disconnection.
• Material 28 composition provides broadband high-frequency EMI/RFI suppression capabilities.
• Free-hanging configuration enables flexible mounting in various spatial constraints.

Applications

• Data transmission modules requiring embedded EMI suppression
• Cable and wiring noise reduction in electronic assemblies
• Common and differential mode interference filtering

Procurement Notes

Verify the specific manufacturer part number against official Laird datasheets to ensure authenticity. Confirm that the received components match the specified Material 28 composition and dimensional tolerances. Check for RoHS3 compliance markings as documented in the product specifications. Ensure storage conditions do not compromise the integrity of the ferrite material or hinge mechanism prior to installation.

Selection Notes

Select this component when retrofitting cables with existing connectors is required due to its split-core design. Choose based on the 13mm internal diameter requirement for cable fitment. Consider the 260 Ohm impedance profile at 100 MHz for target frequency suppression needs. Evaluate space availability for the 33.7mm external length during mechanical integration planning.

Part Context

This component belongs to the 28A series of broadband EMI split cores manufactured by Laird-Signal Integrity Products. The series offers various sizes and impedance values tailored for different cable diameters and noise profiles. These cores are engineered to replace solid cylindrical designs where accessibility is limited, providing comparable performance in high-frequency attenuation.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing cable bundles before substitution attempts.
