74270030

Overview

The Würth Elektronik 74270030 is a WE-AFB series axial ferrite bead designed for EMI suppression. Constructed from 3W800 material, it provides an impedance of 418 ohms at 100 MHz. The cylindrical core features a central hole diameter of 5 mm and an overall length of 16 mm. It is suitable for wires, coaxial cables, and wire-wrapping applications.

Feature Summary

• Axial ferrite bead design for direct cable integration
• Constructed from 3W800 material for effective noise attenuation
• Cylindrical geometry compatible with standard wiring harnesses

Applications

• General electronic equipment noise suppression
• Coaxial cable interference mitigation
• Wire-wrapping circuit protection

Procurement Notes

Verify the specific impedance value against the official datasheet, as distributor listings may vary or contain errors. Confirm that the 5 mm hole diameter accommodates the target cable gauge. Ensure the application environment does not exceed the component's thermal limits. Cross-reference the manufacturer part number to avoid confusion with similar axial beads.

Selection Notes

Select this component when axial installation is required for EMI reduction on cables up to 5 mm in diameter. The 3W800 material offers high impedance at higher frequencies. Compare the 418 ohm impedance requirement against system noise profiles. Consider physical space constraints due to the 16 mm length. Evaluate if snap-on cores are more appropriate for existing assemblies.

Part Context

This component belongs to the WE-AFB series of axial ferrite beads manufactured by Würth Elektronik. These components are distinct from snap-on cores and surface mount inductors. The series focuses on providing simple, effective EMI suppression solutions for through-hole wiring and cable management in electronic assemblies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative axial ferrite beads based on impedance curves and hole diameter specifications before substitution.
