74270035

Overview

The Würth Elektronik 74270035 is a cylindrical axial ferrite bead from the WE-AFB series, designed for EMI suppression. It utilizes 4W620 material composition to provide high impedance against high-frequency noise on cables. The component features a solid free-hanging design suitable for wires and coaxial cables. Key electrical parameters include an impedance of 173 Ω at 25 MHz and 731 Ω at 100 MHz. It operates within a temperature range of -25°C to +105°C.

Feature Summary

• Solid free-hanging cylindrical construction for direct cable mounting
• High impedance performance using 4W620 material composition
• Effective attenuation of high-frequency electromagnetic interference

Applications

• Suppression of noise on signal wires
• EMI filtering for coaxial cables
• Noise reduction in wire-wrapping applications

Procurement Notes

Verify the specific impedance values (173 Ω at 25 MHz and 731 Ω at 100 MHz) match your frequency requirements. Confirm the 4W620 material grade is appropriate for your thermal environment, as the operating range is -25°C to +105°C. Ensure the physical dimensions accommodate the target cable diameter for proper fitment.

Selection Notes

Select this part when high impedance is required at higher frequencies compared to lower-frequency beads. The 4W620 material offers a balance of permeability and resistivity suitable for broadband suppression. Consider the axial form factor if space allows for sliding the core onto the cable before termination.

Part Context

This component belongs to the WE-AFB series of axial ferrite beads manufactured by Wurth Elektronik. These components are engineered specifically for suppressing electromagnetic interference in electronic assemblies. The series provides various impedance profiles to address different noise spectra across power and signal lines.
