7427802

Overview

The Würth Elektronik 7427802 is a solid flat ferrite cable core from the WE-FLAT series, designed for electromagnetic interference suppression on ribbon cables. It features an impedance of 65 Ohms at 100 MHz and utilizes 4W620 ferrite material. The component has internal dimensions of 20 mm length by 0.5 mm thickness, with external dimensions of 23 mm length, 12 mm width, and 3 mm height.

Feature Summary

• Solid construction specifically engineered for flat ribbon cables
• Optimized for high-frequency noise attenuation in digital circuits
• Manufactured using 4W620 ferrite material for consistent performance

Applications

• Electromagnetic interference suppression for flat ribbon cables
• Noise filtering in digital equipment signal lines
• Cable protection in compact electronic assemblies

Procurement Notes

Verify the specific impedance value against official datasheets, as distributor listings may vary between 58 Ohms and 65 Ohms. Confirm RoHS compliance status directly with the manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when space constraints require a low-profile solution for flat cable shielding. Ensure the target application operates within the frequency range where the 65 Ohm impedance provides effective attenuation characteristics for the specific noise profile.

Part Context

This part belongs to the WE-FLAT series of solid ferrite cores. It complements other variants like 74278032 which offer different impedance levels. The series focuses on providing reliable EMI suppression for flexible printed circuit boards and ribbon cables in modern electronics.

Replacement Considerations

Check for direct substitutes within the WE-FLAT series that match the required impedance and physical footprint. Verify dimensional compatibility if replacing with similar flat cores from other manufacturers.
