74270091

Overview

The Wurth Elektronik 74270091 is an EMI suppression axial ferrite bead from the WE-AFB series. Constructed from 3W800 material, it provides a nominal impedance of 170 Ohms at 25 MHz and 386 Ohms at 100 MHz. The component features a cylindrical solid design with a length of 9.5 mm, intended for direct application on wires and coaxial cables to mitigate electromagnetic interference.

Feature Summary

• Provides high-frequency noise attenuation through inherent magnetic properties
• Designed for direct installation onto round cables and wires
• Utilizes 3W800 material composition for stable performance

Applications

• EMI suppression on signal wires
• Noise filtering for coaxial cables
• Interference reduction in wire-wrapping applications

Procurement Notes

Verify the specific impedance requirements against the datasheet curves for 25 MHz and 100 MHz frequencies. Confirm that the cable diameter fits within the core's internal dimensions. Ensure compliance with RoHS standards if required by the target market regulations.

Selection Notes

Select this component when axial ferrite beads are preferred over snap-on types for permanent cable installations. Consider the 170 Ohm impedance at 25 MHz for general EMI suppression needs. Evaluate the 9.5 mm physical size for available space constraints along the cable run.

Part Context

This part belongs to the WE-AFB series of axial ferrite beads manufactured by Wurth Elektronik. These components are distinct from snap-on cores and are designed as solid cylindrical units. They serve as passive components for electromagnetic compatibility in electronic assemblies.
