74270095

Overview

The Würth Elektronik part number 74270095 is an axial ferrite bead from the WE-AFB series, designed for EMI suppression. It features a cylindrical geometry with an inner diameter of 18 mm, an outer diameter of 28 mm, and a height of 28.5 mm. The component utilizes 4W1500 material composition to provide effective noise attenuation in the frequency range between 25 MHz and 100 MHz. It is certified compliant with RoHS and REACH standards.

Feature Summary

• Axial design allows cables to be threaded directly through the center bore for installation.
• Utilizes 4W1500 material formulation optimized for broadband EMI/RFI suppression.
• Cylindrical shape provides uniform magnetic flux distribution around the conductor.

Applications

• Suppression on coaxial cables
• Noise filtering on multi-wire cables
• EMI reduction on general power or signal wires

Procurement Notes

Verify the specific material grade and impedance characteristics against the official datasheet before integration. Confirm that the 18 mm inner diameter accommodates the target cable bundle without excessive strain. Ensure the application environment remains within the operational limits defined by the manufacturer's specifications for the 4W1500 material.

Selection Notes

Select this component when retrofitting existing cabling where snap-on designs are impractical due to large cable diameters. The axial form factor requires threading the cable end, which may impact assembly workflow compared to split-core alternatives. Evaluate the physical space constraints around the cable entry point to ensure the 28 mm outer diameter fits within the enclosure or chassis layout.

Part Context

This component belongs to the WE-AFB series of axial ferrite beads manufactured by Würth Elektronik. These parts are distinct from surface-mount chips or split-core rings, offering a solid core solution for permanent cable treatment. The series focuses on high-performance suppression for applications requiring robust mechanical stability and consistent electromagnetic interference reduction across specified frequency bands.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
