28R1227-100

Overview

The 28R1227-100 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features a rectangular geometry with an inner dimension of 0.975 inches wide by 0.075 inches high (24.77mm x 1.91mm) and an outer width of 1.227 inches (31.17mm). The component has a length of 0.525 inches (13.30mm). It provides an impedance of 128 Ohms at 100MHz.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Rectangular profile optimized for flat or ribbon cable applications
• High impedance performance at 100MHz for effective noise suppression

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise filtering for data transmission lines
• Common mode choke applications in signal integrity management

Procurement Notes

Verify the specific impedance value required for your application against the 128 Ohm specification at 100MHz. Confirm that the inner dimensions of 0.975 inches by 0.075 inches are compatible with the target cable thickness. Ensure compliance with RoHS3 standards if applicable to your manufacturing requirements.

Selection Notes

Select this component when dealing with flat cables requiring significant noise attenuation. The rectangular shape allows for secure placement on non-cylindrical conductors. Consider the physical length of 0.525 inches for space constraints within the assembly.
