7427004

Overview

The Würth Elektronik 7427004 is an axial ferrite bead from the WE-AFB series, designed for EMI suppression. It features a cylindrical NiZn core with dimensions of 14.1 mm outer diameter, 6.3 mm inner diameter, and 28.6 mm length. The component exhibits a DC resistance maximum of 709 Ω and operates effectively within a broadband frequency range up to 100 MHz.

Feature Summary

• Constructed from Nickel-Zinc (NiZn) material suitable for broadband frequency applications
• Axial form factor designed for direct wire insertion and EMI noise reduction
• Solid cylindrical geometry providing structural stability in circuit layouts

Applications

• Electromagnetic interference (EMI) suppression on signal lines
• Power management circuits requiring high-frequency noise attenuation
• Industrial equipment protection against radio frequency interference

Procurement Notes

Verify the specific datasheet version to confirm impedance characteristics at target frequencies. Ensure the axial lead configuration matches the PCB footprint or wire harness requirements. Confirm RoHS compliance status if restricted substances are mandated by the end product regulations.

Selection Notes

Select this component when broadband attenuation is required without significant DC voltage drop. The NiZn composition offers superior performance at higher frequencies compared to MnZn alternatives. Verify that the 709 Ω DC resistance does not interfere with the operational current of the protected circuit trace.

Part Context

This part belongs to the WE-AFB series of EMI suppression ferrite beads manufactured by Würth Elektronik. The series provides various axial ferrite solutions tailored for different impedance and dimensional requirements in electronic assemblies.

Replacement Considerations

Cross-reference with other WE-AFB series parts for similar impedance profiles. Verify physical dimensions and lead spacing compatibility before substituting with components from alternative manufacturers.
