74270056

Overview

The Würth Elektronik part number 74270056 is an EMI suppression axial ferrite bead belonging to the WE-AFB series. It features a solid toroidal core with dimensions of 12 mm outer diameter, 8.5 mm inner diameter, and 15 mm height. The component provides an impedance of 208 Ohms at a test frequency of 100 MHz. Constructed from nickel-zinc ferrite material, it is designed for electromagnetic interference suppression in electronic circuits.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics
• Utilizes nickel-zinc ferrite material suitable for high-frequency noise attenuation
• Features an axial design allowing easy installation on single wires or cables

Applications

• Electromagnetic interface suppression
• General electronic equipment noise filtering
• Cable and wire EMI mitigation

Procurement Notes

Verify that the specific order matches the manufacturer part number 74270056 and the WE-AFB series designation. Confirm compliance with RoHS standards and lead-free requirements as specified by Wurth Elektronik. Ensure the procurement documentation references the correct impedance value of 208 Ohms at 100 MHz to avoid substitution errors with similar ferrite beads.

Selection Notes

Select this component when designing circuits requiring axial ferrite beads for EMI suppression. The 208 Ohm impedance at 100 MHz makes it suitable for attenuating high-frequency noise. Consider the physical dimensions of 12 mm OD and 8.5 mm ID to ensure compatibility with the target cable or wire diameter during integration.
