74270094

Overview

The Wurth Elektronik 74270094 is an axial ferrite bead from the WE-AFB series, designed for EMI suppression on wires and coaxial cables. It utilizes 4W620 material to provide high impedance in the radio frequency range. The component features a cylindrical core with a 10.7 mm outer diameter and 35 mm length. It exhibits an impedance of 110 Ω at 100 MHz and 40 Ω at 25 MHz. The part is RoHS compliant and suitable for general electronic applications requiring cable noise reduction.

Feature Summary

• Axial ferrite bead design for direct wire integration
• High impedance performance using 4W620 material composition
• Suitable for suppressing electromagnetic interference on coaxial cables

Applications

• EMI suppression on signal wires
• Noise filtering for coaxial cables
• Wire-wrapping applications

Procurement Notes

Verify the specific impedance requirements against the 4W620 material datasheet before procurement. Confirm that the axial form factor aligns with the assembly process. Ensure compliance with RoHS standards if required by the end product regulations. Cross-reference the 110 Ω@100MHz specification with system noise profiles to validate effectiveness.

Selection Notes

Select this component when axial mounting is preferred over snap-on cores for cable management. The 10.7 mm diameter accommodates standard wire gauges without excessive bulk. Choose based on the need for broadband attenuation in the VHF/UHF ranges provided by the 4W620 formulation. Consider mechanical stability during installation compared to split-core alternatives.
