7427806

Overview

The Würth Elektronik 7427806 is a solid flat ferrite core from the WE-FLAT series, designed for suppressing electromagnetic interference in flexible printed circuit boards. It features a nominal impedance of 65 Ω at 100 MHz and measures 41.5 mm in width by 0.5 mm in thickness. The component utilizes high-permeability ferrite material to provide effective common-mode noise attenuation without requiring additional mounting hardware.

Feature Summary

• Solid design eliminates the need for fasteners or clips during installation
• Optimized geometry for direct application on flexible printed circuits
• Provides targeted impedance characteristics for high-frequency noise suppression

Applications

• Flexible printed circuit board (FPC) noise suppression
• General electronic equipment signal line filtering
• Compact digital device cable shielding

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the solid construction meets the mechanical constraints of the target assembly. Ensure compliance with relevant environmental directives applicable to the final product deployment region.

Selection Notes

Select this component when space constraints prevent the use of traditional snap-on cores. The flat profile suits applications where standard cylindrical ferrites cannot fit between circuit board layers or connectors. Evaluate the 65 Ω impedance requirement against the noise spectrum of the specific signal lines being protected.

Part Context

This part belongs to the WE-FLAT series, which specializes in low-profile ferrite solutions for modern electronics. Unlike split-core variants, these solid units offer consistent magnetic properties without air gaps introduced by clamping mechanisms. The series supports miniaturization trends in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 65 Ω impedance at 100 MHz and similar physical footprint. Verify that alternative solid flat cores maintain comparable saturation characteristics and temperature stability for equivalent performance.
