28R1127-400

Overview

The Laird-Signal Integrity Products 28R1127-400 is a split, snap-on cable ferrite core designed for broadband electromagnetic interference (EMI) filtering. It features a lightweight plastic case construction and operates in a free-hanging mounting configuration. The component has an inner dimension of 0.925 inches wide by 0.067 inches high (23.50mm x 1.70mm) and an outer dimension of 1.125 inches wide by 0.303 inches high (28.58mm x 7.70mm).

Feature Summary

• Split design allows installation onto existing cables without disconnecting terminals.
• Snap-on mechanism enables rapid deployment on wires.
• Lightweight plastic housing reduces overall assembly weight.

Applications

• Suppressing unintended signals on cables.
• Filtering signals being emitted from wires.
• Broadband EMI filtering applications.

Procurement Notes

Verify the specific part number suffix to ensure correct dimensional compatibility with target cables. Confirm that the split-core design meets the mechanical requirements for the intended harness routing. Check manufacturer documentation for environmental ratings and material specifications relevant to the operating environment.

Selection Notes

Select this component when retrofitting EMI suppression onto existing wire assemblies is required. Ensure the cable diameter fits within the specified inner dimensions of 23.50mm width and 1.70mm height. Consider the physical space constraints relative to the outer dimensions of 28.58mm by 7.70mm during layout planning.

Part Context

This component belongs to the cable ferrite category manufactured by Laird-Signal Integrity Products. It serves as a passive filter element to mitigate high-frequency noise on conductors. The product utilizes a solid magnetic material encased in a protective plastic shell to provide durability while maintaining effective attenuation characteristics across a broad frequency spectrum.
