28R0480-000

Overview

The Laird-Signal Integrity Products 28R0480-000 is a solid flat ribbon cable ferrite core designed for electromagnetic interference suppression. It exhibits an impedance of 190 Ohms at a test frequency of 100 MHz. The component features an internal slot measuring 8 mm in width and 1 mm in height, accommodating flat ribbon cables. External dimensions are 12.2 mm in length, 8 mm in width, and 5.5 mm in height. Constructed from material grade 28, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Solid construction with a flat rectangular profile optimized for ribbon cable integration
• Provides high impedance attenuation at 100 MHz to suppress common mode noise
• Compatible with standard flat ribbon cable geometries via precise internal slot dimensions

Applications

• Electromagnetic interference filtering on flat ribbon cables
• Signal integrity enhancement in data transmission lines
• Common mode noise suppression in electronic assemblies

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm impedance characteristics and physical dimensions, as variations exist within the product family. Ensure the selected variant matches the required ribbon cable thickness and width specifications for proper mechanical fit. Confirm RoHS compliance status and material composition details prior to final procurement decisions.

Selection Notes

Select this component when flat ribbon cable geometry requires integrated EMI suppression without additional mounting hardware. The solid design eliminates assembly complexity compared to split-core alternatives. Evaluate the 190 Ohm impedance value against target noise frequencies to ensure effective attenuation. Verify that the internal slot dimensions align precisely with the specific ribbon cable gauge being utilized in the design.

Part Context

This part belongs to the 28R series of solid ferrite cores manufactured by Laird-Signal Integrity Products. The series offers various impedance values and physical sizes tailored for different cable types. The 28R0480-000 specifically addresses applications requiring robust noise filtering for flat ribbon configurations, distinguishing itself through its fixed solid structure and standardized dimensional tolerances.

Replacement Considerations
