7427006

Overview

The Würth Elektronik 7427006 is a cylindrical ferrite cable core from the WE-AFB series, designed for electromagnetic interference suppression. It features an inner diameter of 8.5 mm, an outer diameter of 12 mm, and a length of 15 mm. The component utilizes nickel-zinc material (grade 4W620) to provide an impedance of 70 Ω at a test frequency of 100 MHz. It operates within a frequency range of 25 MHz to 100 MHz and weighs approximately 4 grams.

Feature Summary

• Provides effective electromagnetic interference suppression through high-impedance characteristics in the specified frequency band.
• Constructed from durable nickel-zinc ferrite material suitable for solid cable applications.
• Designed as a free-hanging component for easy installation on cables without additional mounting hardware.

Applications

• Electromagnetic interface noise reduction
• Cable filtering for electronic equipment
• EMI suppression on signal and power lines

Procurement Notes

Verify the specific impedance tolerance and material grade against the official datasheet before integration. Confirm that the 8.5 mm inner diameter accommodates the target cable bundle size with appropriate clearance. Ensure compliance with REACH and RoHS standards if required by the end-product regulations. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a 70 Ω impedance at 100 MHz is required for EMI mitigation. The 8.5 mm bore size dictates the maximum cable diameter it can accommodate. Consider the physical dimensions of 12 mm outer diameter and 15 mm length for spatial constraints in the assembly. The nickel-zinc composition offers stability across the operating frequency range.

Part Context

This part belongs to the WE-AFB series of axial ferrite beads manufactured by Würth Elektronik. These cores are engineered for general-purpose EMI suppression tasks. The series provides various impedance values and physical sizes to suit different cable diameters and frequency requirements. The 7427006 specifically targets applications requiring moderate impedance in the VHF range.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing designs if considering alternative manufacturers or series.
