28R1517-000

Overview

The 28R1517-000 is a solid flat ribbon cable ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 230 Ohms at a test frequency of 100 MHz. The component features internal dimensions of 26.67 mm in length and 1.91 mm in height, with external dimensions measuring 38.1 mm in length and 12.07 mm in height. An external width of 25.4 mm accommodates ribbon cables. Constructed from material grade 28, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Solid construction designed for flat ribbon cable applications
• High impedance performance at 100 MHz for EMI suppression
• Wide operating temperature capability for diverse environments

Applications

• Electromagnetic interference filtering on flat ribbon cables
• Signal integrity enhancement in wiring harnesses
• Noise reduction in electronic equipment cabling

Procurement Notes

Verify the specific part number 28R1517-000 against official Laird datasheets to confirm impedance and dimensional accuracy. Ensure compatibility with existing ribbon cable widths before integration. Check for RoHS compliance status if required by project specifications. Confirm that the solid design meets mechanical constraints for the intended assembly location.

Selection Notes

Select this component when high impedance is required specifically for flat ribbon cables rather than round wires. The solid design offers structural stability compared to split cores. Consider the 230 Ohm impedance value relative to the noise frequencies present in the application. Verify that the physical dimensions fit within the available space for cable routing.

Part Context

This ferrite core belongs to the 28 series of signal integrity products from Laird. It is categorized under cable ferrites and is distinct from chip bead inductors or round wire cores. The product line focuses on providing passive filtering solutions for high-speed digital signals and power lines using ferrite materials.

Replacement Considerations
