28R2992-000

Overview

The 28R2992-000 is a solid ferrite cable core manufactured by Laird-Signal Integrity Products, designed for electromagnetic interference suppression. It exhibits an impedance of 161 Ohms at a test frequency of 100 MHz. The component features a rectangular geometry with an internal slot measuring 29.92 mm in length and an external length of 35.56 mm. The external width is 31.75 mm, while the external height is 12.70 mm. The internal height is specified as 3.18 mm. Constructed from material grade 28, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Solid construction provides stable magnetic properties for consistent noise attenuation across varying environmental conditions.
• Rectangular design with a dedicated internal slot facilitates easy installation around flat ribbon cables and wire bundles without disconnection.

Applications

• Suppression of electromagnetic interference on flat ribbon cables in data transmission systems
• Noise filtering for wire bundles in industrial control equipment
• EMI reduction in computer peripheral interconnects

Procurement Notes

Verify the specific impedance value and physical dimensions against the official manufacturer datasheet prior to integration. Confirm that the internal slot dimensions accommodate the target cable thickness without mechanical stress. Ensure compliance with RoHS3 regulations and check for any specific REACH status requirements relevant to your region. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when high impedance at 100 MHz is required for broadband noise suppression on larger gauge or flat cabling. The solid core design eliminates the need for assembly hardware, simplifying the manufacturing process compared to split cores. Consider the operating temperature range and material grade to ensure compatibility with the thermal environment of the final application.

Part Context

This component belongs to the 28R series of ferrite cable cores from Laird-Signal Integrity Products. The series utilizes material grade 28, optimized for high-frequency noise absorption. These cores are distinct from bead types as they are designed to encircle existing cables rather than being placed inline during circuit board assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify dimensional compatibility and impedance characteristics if considering alternatives from other manufacturers.
