28A0640-0A0

Overview

The 28A0640-0A0 is a hinged clamp-on ferrite core manufactured by Laird-Signal Integrity Products. It utilizes material grade 28 to provide an impedance of 240 Ohms at 100 MHz. The component features a round shape with a 9.8 mm inner diameter and external dimensions of 20.07 mm width, 21.65 mm height, and 41.4 mm length. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Hinged snap-on design for easy installation on cables without disconnection
• High impedance performance using material grade 28 composition
• Round geometry suitable for cylindrical cable profiles

Applications

• Suppression of electromagnetic interference on power cables
• Noise filtering in signal transmission lines
• Compliance enhancement for electronic equipment emissions

Procurement Notes

Verify the specific manufacturer designation, as some sources list Qnity while others cite Laird. Confirm the exact inner diameter specification (9.8 mm vs 9.07 mm) against your cable requirements. Ensure the material grade 28 matches your frequency attenuation needs. Check RoHS compliance status details provided by the supplier.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. The hinged design allows retrofitting onto existing assemblies. Ensure the target cable diameter fits within the 9.8 mm internal clearance. Consider the operating temperature range of -40°C to +125°C for environmental suitability.

Part Context

This part belongs to the 28A series of ferrite clamp-on cores from Laird-Signal Integrity Products. These components are designed for broadband noise suppression. The 28A series typically offers high permeability materials optimized for common mode noise reduction in various industrial and commercial applications.

Replacement Considerations
