28A0434-0A2

Overview

The Laird-Signal Integrity Products 28A0434-0A2 is a broadband split snap-on ferrite core designed for EMI suppression on round cable assemblies. It features a hinged design for easy installation without disconnecting cables. The component provides excellent common and differential mode noise reduction. Key electrical parameters include an impedance of 277 ohms at 100 MHz. Physical dimensions are approximately 14.71 mm in outer diameter and 43.03 mm in length. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Hinged snap-on construction allows for rapid installation on existing cable assemblies without disconnection.
• Provides effective broadband suppression for both common-mode and differential-mode electromagnetic interference.
• Constructed from ultra-thin mixtures of iron, nickel, and zinc oxides for optimized high-frequency performance.

Applications

• Suppression of high-frequency EMI on electronic wires and cables
• Noise reduction on round cable assemblies in industrial equipment
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the hinged mechanism remains secure during operation. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when non-invasive installation on pre-existing cabling is required. The split design eliminates the need to thread cables through solid cores. Consider the inner diameter compatibility with the target cable bundle. Evaluate the impedance profile at the specific noise frequencies of interest to ensure adequate attenuation.
