28A2025-0A2

Overview

The Laird-Signal Integrity Products 28A2025-0A2 is a hinged, snap-on cable ferrite core from the 28A series. It features a circular design with external dimensions of 18.15mm width by 18.90mm height and a length of 32.50mm. The internal aperture measures 7.05mm by 3.40mm. Constructed from material grade 28, it provides an impedance of 320 Ohms at 100MHz, 130 Ohms at 25MHz, and 510 Ohms at 300MHz. The component supports free-hanging installation and complies with RoHS3 standards.

Feature Summary

• Hinged snap-on design for easy installation around existing cables
• Circular form factor suitable for round cable applications
• Material grade 28 composition for broadband EMI suppression

Applications

• Electromagnetic interference suppression on cables
• Broadband noise filtering in signal integrity circuits

Procurement Notes

Verify the specific impedance requirements against the frequency spectrum of your application to ensure compatibility with the 28A series characteristics. Confirm that the target cable diameter fits within the specified internal aperture dimensions of 7.05mm by 3.40mm. Check for RoHS3 compliance if required by your manufacturing standards. Ensure the hinged mechanism is suitable for the intended mounting environment.

Selection Notes

Select this component when a reusable, snap-on ferrite solution is required for cable noise reduction. The 28A series offers high impedance across a broad frequency range. Consider the physical size constraints and the need for a hinged design versus solid cores. Verify that the internal dimensions accommodate the specific cable bundle diameter effectively.

Part Context

This part belongs to the Laird 28A series of broadband EMI split/snap-on ferrite cable cores. These components are designed for suppressing electromagnetic interference on cables and wiring. The series utilizes various material grades to optimize performance across different frequency bands, with the 28A2025-0A2 specifically utilizing material grade 28.

Replacement Considerations

Direct substitutes within the same series include parts like 28A0593-0A2 or 28A4155-0A2, though these differ significantly in internal aperture size and impedance values. Ensure any replacement matches the required internal dimensions and impedance profile for the specific cable and frequency application.
