28R1128-100

Overview

The 28R1128-100 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 204 Ohms at 100 MHz and utilizes Material 28 for noise suppression. The component features a circular design with an inner diameter of 2.00 mm, an outer diameter of 4.00 mm, and a length of 10.00 mm. It is classified as a cable ferrite suitable for surface mounting applications.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Utilizes Material 28 composition for effective high-frequency noise attenuation
• Circular geometry allows easy sliding onto existing wire harnesses

Applications

• Suppression of electromagnetic interference in power cables
• Noise filtering for signal transmission lines
• Compliance enhancement for electronic equipment EMC requirements

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the inner diameter accommodates the target cable bundle without excessive friction. Ensure the application environment does not exceed the thermal limits specified for Material 28 components during operation.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable treatment. The 204 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Consider the physical dimensions to ensure adequate clearance around the cable assembly during routing and enclosure fitting.

Part Context

This part belongs to the 28R series of cable ferrites from Laird-Signal Integrity Products. These cores are engineered for broadband noise suppression using specialized ferrite materials. The series offers various impedance values and physical sizes to match different cable diameters and frequency requirements.

Replacement Considerations

Direct substitutes include other solid ferrite cores with matching 2.00 mm inner diameter and similar 200+ Ohm impedance at 100 MHz. Verify cross-compatibility with Material 28 specifications to maintain equivalent noise performance characteristics.
