28A2029-0A0

Overview

The Laird-Signal Integrity Products 28A2029-0A0 is a split ferrite clamp-on core designed for cable noise suppression. It utilizes Material 28 composition to provide an impedance of 250 Ohms at 100 MHz. The component features a hinged snap-on design with a rectangular inner cavity measuring 10.00 mm by 4.30 mm and an outer dimension of 22.28 mm by 21.84 mm. It operates within a temperature range of -40°C to +125°C.

Feature Summary

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

Applications

• Suppression of electromagnetic interference on data and power cables
• Noise filtering in telecommunications equipment signal lines
• EMI mitigation in automotive wiring harnesses

Procurement Notes

Verify the specific suffix code against official datasheets, as variations may indicate different material grades or color codes. Confirm that the internal dimensions match the target cable diameter precisely to ensure proper fit and magnetic coupling efficiency. Check RoHS compliance status if required by regional regulations.

Selection Notes

Select this model when retrofitting noise suppression onto finished assemblies is necessary due to its split-core architecture. Ensure the operating frequency of interest aligns with the peak impedance characteristics of Material 28. Validate that the physical clearance accommodates both the cable bundle and the core's outer dimensions within the enclosure.

Part Context

This component belongs to the 28A series of ferrite cores manufactured by Laird-Signal Integrity Products. The series offers various sizes and materials optimized for broadband noise reduction. The 28A designation typically refers to the specific geometry and hinge mechanism style used across this product line.

Replacement Considerations

Direct substitutes include part numbers with identical Material 28 specifications and matching dimensional tolerances. Verify that alternative split-core designs maintain the same impedance profile at 100 MHz to ensure equivalent performance in the application.
