28A2913-0A2

Overview

The Laird-Signal Integrity Products 28A2913-0A2 is a hinged snap-on ferrite core designed for broadband EMI suppression. It features an impedance of 177 Ohms at 100MHz and utilizes material grade 28. The component has a circular design with a free-hanging installation type. Internal dimensions are 0.514 inches (13.06mm) diameter, while external dimensions measure 0.925 inches (23.50mm) diameter and 1.427 inches (36.25mm) in length.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cable assemblies without disconnection.
• Provides effective common and differential mode EMI suppression on round cables.
• Utilizes high-performance magnetic material for broadband noise reduction.

Applications

• Suppression of electromagnetic interference on round cable assemblies
• RFI mitigation in electronic systems requiring signal integrity
• Broadband noise filtering for data and power lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet to ensure compatibility with target cable diameters. Confirm RoHS compliance status and check for any recent product change notices that may affect specifications or availability before finalizing procurement orders.

Selection Notes

Select this part when a non-invasive solution for cable noise suppression is required. The hinged mechanism facilitates retrofitting onto installed wiring. Ensure the inner diameter accommodates the cable bundle size and verify that the 177 Ohm impedance profile matches the frequency spectrum of the interference being targeted.

Part Context

This component belongs to the 28A series of split/snap-on ferrite cores from Laird-Signal Integrity Products. These cores are engineered for signal integrity applications, offering a practical alternative to solid cores that require cable termination removal. The series is widely used in industrial and commercial electronics for EMI control.

Replacement Considerations

Direct substitutes within the same series include parts like 28A0593-0A2 or 28A2025-0A2, though impedance and dimensional differences must be evaluated. Verify that any replacement maintains the required inner diameter clearance and provides equivalent attenuation characteristics at the critical frequencies of operation.
