7427254

Overview

The Würth Elektronik part number 7427254 is a split flat ferrite core designed for electromagnetic interference suppression. It belongs to the WE-SFA series and utilizes 4W620 material composition. The component features an openable design suitable for flat ribbon cables, accommodating up to one wire within its internal dimensions of 65.30 mm width by 2.00 mm height. Its external dimensions measure 76.20 mm in width and 13.00 mm in height. The impedance at 100 MHz is specified as 114 Ohms. The unit weight is not explicitly defined in the provided source data.

Feature Summary

• Split flat design allows for easy installation onto existing cable assemblies without disconnecting wires.
• Utilizes 4W620 ferrite material optimized for high-frequency noise attenuation.
• Specifically engineered for flat ribbon cables with precise internal aperture dimensions.

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Signal integrity enhancement in high-speed digital interfaces
• Noise reduction in compact electronic device interconnects

Procurement Notes

Verify the exact impedance value and frequency response characteristics against the official datasheet before integration. Confirm that the internal aperture dimensions match the specific flat cable thickness being utilized. Ensure compliance with RoHS requirements if mandated by the end-product specifications. Cross-reference the material grade 4W620 for thermal stability within the intended operating environment.

Selection Notes

Select this component when dealing with flat ribbon cables requiring non-invasive EMI mitigation. The split design facilitates retrofits or modifications to existing harnesses. Consider the 114 Ohm impedance at 100 MHz for compatibility with target noise frequencies. Evaluate the physical footprint constraints against the external dimensions of 76.20 mm by 13.00 mm to ensure adequate clearance within the assembly.

Part Context

This component is part of the WE-SFA series from Würth Elektronik, focusing on flat cable solutions. It complements other ferrite products like the 742725 solid cores and 7427254 split variants. The series addresses diverse cable geometries, offering both solid and openable options for different installation scenarios and noise profiles.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 4W620 material properties, 114 Ohm impedance at 100 MHz, and compatible internal aperture dimensions for the specific flat cable application.
