28A0392-0A2

Overview

The Laird-Signal Integrity Products 28A0392-0A2 is a broadband split snap-on ferrite core designed for round cable assemblies. It utilizes Material 28 to provide effective EMI suppression in both common and differential modes. The component features a hinged design for easy installation without disconnecting cables. Key electrical parameters include an impedance of 170 Ohms at 100 MHz. Physical dimensions are approximately 1.203 inches (30.56 mm) in length, with an outer width of 0.540 inches. The internal cavity accommodates specific cable diameters, and the unit operates within a temperature range of -40°C to +125°C.

Feature Summary

• Hinged snap-on design allows installation on existing cable assemblies without disconnection
• Provides broadband EMI suppression for both common and differential mode noise
• Constructed from Material 28 ferrite composition for high-frequency performance

Applications

• Suppression of electromagnetic interference on round cable assemblies
• Common mode noise reduction in signal and power lines
• Differential mode noise filtering in electronic interconnects

Procurement Notes

Verify the specific inner diameter requirements against the target cable assembly to ensure proper fitment, as the split-core design relies on precise clearance. Confirm that the Material 28 specification aligns with the intended frequency range of noise suppression. Check RoHS compliance status if required by project specifications. Ensure the operating temperature range meets environmental conditions. Validate the impedance value at the relevant test frequency for circuit compatibility.

Selection Notes

Select this component when non-invasive installation on pre-assembled round cables is required. The split design eliminates the need to thread cables through solid cores. Material 28 offers a balance of permeability and resistivity suitable for broadband applications. Consider the physical size constraints of the enclosure or routing path. Evaluate the impedance profile at the dominant noise frequencies to ensure adequate attenuation.

Part Context

This part belongs to the 28A series of cable ferrites from Laird-Signal Integrity Products. The series focuses on snap-on cores for versatile deployment. Material 28 is a standard ferrite formulation used across multiple product lines for general-purpose EMI suppression. The 28A0392-0A2 represents a specific size and impedance variant within this broader family of components.

Replacement Considerations

Direct substitutes must match the 170 Ohm impedance at 100 MHz and the Material 28 composition. Verify that alternative split-core designs have compatible inner diameters for the specific cable being treated. Ensure the replacement maintains the same hinged mechanical structure for ease of use. Cross-reference physical dimensions to confirm spatial compatibility in the assembly.
