28A0593-0A2

Overview

The Laird-Signal Integrity Products 28A0593-0A2 is a cylindrical, split-core ferrite suppressor designed for broadband EMI suppression on round cable assemblies. It utilizes Material 28 to provide effective common and differential mode noise reduction across the 25 MHz to 300 MHz frequency range. The component features a hinged design for easy installation without disconnecting cables. Key electrical specifications include an impedance of 407 ohms at 100 MHz. Physical dimensions consist of an inner diameter of 6.76 mm (0.266 inches) and an outer diameter of 18.75 mm (0.738 inches), with a total length of 52.91 mm (2.083 inches).

Feature Summary

• Split core design allows installation around existing cables without disconnection.
• Provides broadband EMI suppression for both common and differential modes.
• Hinged mechanism ensures secure closure and free-hanging mounting.

Applications

• Suppression on round cable assemblies in electronic equipment.
• Noise reduction in high-frequency signal lines operating between 25 MHz and 300 MHz.
• EMI mitigation in industrial or commercial wiring harnesses.

Procurement Notes

Verify the specific material grade (Material 28) and impedance characteristics against your target frequency requirements. Confirm that the inner diameter of 6.76 mm accommodates the cable bundle size. Ensure the hinged mechanism integrity is suitable for the intended environmental conditions. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when broadband suppression is needed for round cables without breaking the circuit. The 407 ohm impedance at 100 MHz makes it suitable for higher frequency noise compared to lower impedance cores. Consider the physical length and diameter constraints within the assembly. The split design is critical for retrofitting or maintaining existing cable runs.

Part Context

This part belongs to the Laird 28A series of broadband EMI split/snap-on ferrite cable cores. These components are engineered for signal integrity applications where compact, non-invasive noise filtering is required. The series offers various material compositions and impedance values to address different frequency-specific interference problems in modern electronics.

Replacement Considerations

Direct substitutes must match the 407 ohm @ 100 MHz impedance, 6.76 mm inner diameter, and Material 28 composition. Verify that any replacement also features a hinged, split-core design for identical installation methods. Cross-reference physical dimensions to ensure fitment within the available space.
