28A2025-000

Overview

The Laird-Signal Integrity Products 28A2025-000 is a hinged snap-on ferrite core designed for cable noise suppression. It features a round shape with an internal diameter of 6.60 mm and external dimensions of 15.00 mm width by 7.50 mm height. The component has a length of 32.50 mm and utilizes material grade 28. Impedance specifications include 130 Ohms at 25 MHz, 320 Ohms at 100 MHz, and 510 Ohms at 300 MHz. The maximum DC resistance is 170 Ohms. It operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Hinged snap-on design allows installation on cables without disconnecting terminals
• Round geometry accommodates cylindrical cable profiles
• Material grade 28 provides high permeability for effective EMI attenuation

Applications

• Electromagnetic interference suppression on signal and power cables
• Noise filtering in electronic equipment cabling
• Cable harness management for signal integrity enhancement

Procurement Notes

Verify the specific impedance requirements against the application frequency spectrum before procurement. Confirm that the cable diameter falls within the 6.60 mm internal diameter specification to ensure proper fit. Check for compliance with local environmental regulations such as RoHS3 and REACH status. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Selection Notes

Select this component when non-invasive cable modification is required for noise reduction. The hinged mechanism distinguishes it from split cores that require sliding onto the cable end. Consider the physical size constraints of the enclosure relative to the 32.50 mm length. Evaluate the impedance profile at target frequencies to ensure sufficient attenuation for the specific noise sources present in the system.

Part Context

This part belongs to the 28A series of cable ferrites manufactured by Laird-Signal Integrity Products. It is functionally similar to the 28A2025-0A2 variant but may differ in packaging or specific manufacturing batch details. The series is characterized by snap-on ferrite cores used for broadband noise suppression in various electronic applications.

Replacement Considerations

The 28A2025-0A2 is a related variant within the same product family. Verify dimensional compatibility and impedance characteristics before substitution. Other split-core ferrites with similar internal diameters may serve as alternatives if mechanical mounting permits.
