28A4155-0A2

Overview

The Laird-Signal Integrity Products 28A4155-0A2 is a hinged snap-on ferrite core designed for cable EMI suppression. It features Material 28 with an impedance of 120 Ohms at 100MHz. The component has a round shape and free-hanging installation type. Internal dimensions include a 0.591-inch (15.00mm) diameter bore. External dimensions are 1.307 inches wide by 1.134 inches high (33.20mm x 28.80mm), with a length of 0.858 inches (21.80mm).

Feature Summary

• Hinged snap-on design allows for easy installation on existing cables without disconnection.
• Provides effective common and differential mode EMI suppression on round cables.
• Constructed from Material 28 ferrite composition for broadband noise attenuation.

Applications

• Cable EMI suppression in electronic assemblies
• Signal integrity improvement for round cables
• High frequency noise filtering in industrial equipment

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct material grade and dimensional specifications. Confirm RoHS compliance status and REACH registration requirements prior to procurement. Cross-reference datasheet parameters with actual component markings to prevent substitution errors during assembly integration.

Selection Notes

Select this component when retrofitting EMI suppression onto existing cabling is required due to its hinged construction. Ensure the cable diameter fits within the 15.00mm internal bore. Consider the 120 Ohm impedance at 100MHz for target noise frequencies. Evaluate spatial constraints against the external dimensions of 33.20mm width and 28.80mm height.

Part Context

This component belongs to the Laird 28 series of split ferrite cores. These cores are engineered as alternatives to solid cylindrical designs, offering comparable performance while facilitating post-manufacturing installation.
