28B1122-300

Overview

The 28B1122-300 is a solid, free-hanging cable ferrite core manufactured by Laird-Signal Integrity Products. It utilizes material 28 to provide an impedance of 210 Ohms at 100 MHz. The component features a circular design with an inner diameter of 0.542 inches (13.77 mm), an outer diameter of 1.122 inches (28.50 mm), and a length of 0.787 inches (20.00 mm). It is classified under the 28B series and is currently in active production.

Feature Summary

• Solid construction for stable electromagnetic interference suppression
• Free-hanging mounting style suitable for various cable configurations
• Material 28 composition optimized for high-frequency noise attenuation

Applications

• Cable and wiring EMI filtering
• High-frequency noise suppression in electronic assemblies
• Signal integrity enhancement for data lines

Procurement Notes

Verify the specific impedance value of 210 Ohms at 100 MHz against your circuit requirements. Confirm that the physical dimensions, particularly the 13.77 mm inner diameter, accommodate the target cable gauge. Ensure compliance with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number 28B1122-300 to avoid confusion with similar series components.

Selection Notes

Select this component when high impedance is required for cables with diameters up to 13.77 mm. The Material 28 formulation is distinct from other series options, offering specific frequency characteristics. Consider the free-hanging form factor for applications where snap-on or clamp mechanisms are not preferred. Evaluate the physical size constraints to ensure the 28.50 mm outer diameter fits within the enclosure.
