7427217

Overview

The Würth Elektronik 7427217 is a WE-FLAT series flat cable ferrite core designed for suppressing electromagnetic interference in ribbon cables. Constructed from 4W620 material, it accommodates up to 26 wires within an inner cross-section of 34.8 mm by 1.3 mm. The component provides an impedance of 52 Ohms at 100 MHz. External dimensions are 40 mm width, 6.5 mm height, and 1 mm length. It complies with RoHS and REACH standards.

Feature Summary

• Accommodates flat ribbon cables with up to 26 conductors
• Utilizes 4W620 magnetic material for effective noise suppression
• Provides high impedance at 100 MHz for EMI reduction

Applications

• General electronics applications
• Flat ribbon cable noise suppression
• Data transmission line filtering

Procurement Notes

Verify the specific impedance value against the latest official datasheet, as sources indicate variations between 48 Ohms and 55 Ohms. Confirm that the internal dimensions match the target cable thickness of 1.3 mm. Ensure compliance requirements for RoHS and REACH are met for the intended market. Check current manufacturing lead times before finalizing procurement plans.

Selection Notes

Select this component when shielding multi-conductor flat cables is required. The 4W620 material offers suitable performance for general EMI suppression. Ensure the cable bundle fits within the 34.8 mm by 1.3 mm aperture. Consider the external size constraints for the assembly space. Verify the impedance requirement aligns with system noise frequencies.

Part Context

This part belongs to the WE-FLAT series of flat ferrite cores from Würth Elektronik. These components are specifically engineered for ribbon cables rather than round wires. The series utilizes standardized magnetic materials like 4W620 to provide consistent attenuation characteristics across various electronic assemblies.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify compatibility based on internal dimensions, material properties, and impedance specifications when seeking alternatives.
