74270061

Overview

The Würth Elektronik 74270061 is an axial ferrite bead from the WE-AFB series, designed for electromagnetic interference suppression. Constructed from 4W1500 material, it provides a high impedance of 430 Ω at 100 MHz and 85 Ω at 25 MHz. The component features a cylindrical shape with a maximum cable diameter of 6 mm. It is suitable for use with wires, coaxial cables, and wire-wrapping applications to mitigate noise in electronic circuits.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics
• Axial design allows for easy integration into wire and cable assemblies
• Constructed from specialized 4W1500 ferrite material for consistent performance

Applications

• Suppression on individual wires
• Noise reduction on coaxial cables
• EMI filtering for wire-wrapping connections

Procurement Notes

Verify the specific impedance values against your schematic requirements, as the 74270061 offers 430 Ω at 100 MHz. Confirm that the target cable diameter does not exceed the 6 mm maximum limit. Ensure the axial form factor fits within the available spatial constraints of the assembly. Cross-reference the 4W1500 material specification to guarantee compatibility with the intended frequency range of interference.

Selection Notes

Select this component when high attenuation is required at 100 MHz for small-diameter conductors. The 430 Ω impedance makes it distinct from lower-impedance alternatives in the same series. Consider the axial geometry for direct wire application rather than snap-on ring designs. Validate that the 6 mm inner diameter accommodates the specific cable or wire bundle being treated.

Part Context

This part belongs to the WE-AFB series of axial ferrite beads manufactured by Würth Elektronik. These components are engineered specifically for EMI suppression tasks where traditional surface-mount or through-hole beads are unsuitable due to the nature of the cabling. The series utilizes proprietary ferrite materials optimized for broadband noise absorption.

Replacement Considerations

Direct substitutes must match the 430 Ω @ 100 MHz impedance and 6 mm diameter constraint. Verify if alternative axial ferrite beads from other manufacturers offer compatible 4W1500 material properties. Ensure any replacement maintains the same physical length and core geometry for mechanical fit.
