28R1476-100

Overview

The 28R1476-100 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It utilizes Material 28 to provide an impedance of 110 Ohms at 100 MHz. The component features a flat rectangular geometry with an inner dimension of 1.358 inches wide by 0.039 inches high (34.50mm x 1.00mm). The outer dimensions are 1.476 inches wide by 0.157 inches high (37.50mm x 4.00mm), and the length is 0.394 inches (10.00mm). It is designed for through-hole or free-hanging installation on cables.

Feature Summary

• Solid construction made from Material 28 ferrite composition
• Free-hanging design suitable for cable wrapping
• Flat profile optimized for specific cable geometries

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Common mode noise filtering in signal lines
• Cable assembly EMI mitigation

Procurement Notes

Verify the exact inner width and height specifications against the target cable bundle diameter before ordering. Confirm that the solid core design meets the mechanical strain requirements of the application. Check RoHS3 compliance status if required by regional regulations. Ensure the 110 Ohm impedance characteristic aligns with the noise frequency spectrum of the system.

Selection Notes

Select this part when a flat, solid ferrite core is required for cables with a width near 34.50mm. The Material 28 composition offers specific permeability characteristics distinct from other series. Compare the 110 Ohm impedance value against alternative frequencies if the noise spectrum differs significantly from 100 MHz. Consider the physical bulk compared to split cores if frequent disassembly is needed.

Part Context

This component belongs to the 28R series of cable ferrites from Laird-Signal Integrity Products. It is categorized as a passive filter element used for signal integrity enhancement. The product is currently active and available for procurement. It serves as a solution for radiated emission control in electronic assemblies.

Replacement Considerations
