Wurth Elektronik WE-AFB Series Ferrite Ring, 14.1mm Outside Diameter, 6.3mm Inside Diameter - 7427004
This ferrite ring is designed to reduce electromagnetic interference in cable assemblies and wire harnesses. Intended for use around coaxial cable and multiconductor conductors, it operates effectively across a band of higher frequencies commonly encountered in signal and power lines. The component is constructed from 4W620 material and meets common environmental substance regulations, making it suitable for integration into electronic systems requiring controlled suppression of conducted noise.
Features and Benefits:
• Operates across 25MHz to 100MHz for targeted noise suppression
• Axial bead form provides straightforward installation on cables
• 4W620 material composition enhances high‑frequency attenuation
• Complies with RoHS and REACH to support material compliance needs
• Compact height enables use in confined routing spaces
• Axial bead form provides straightforward installation on cables
• 4W620 material composition enhances high‑frequency attenuation
• Complies with RoHS and REACH to support material compliance needs
• Compact height enables use in confined routing spaces
Applications
• Suitable for wrapping cable to reduce conducted interference
• Ideal for ferrite choke use on coaxial cable assemblies
• Used with multiconductor wire in signal integrity mitigation
• Can be used for axial suppression on single‑core conductors
• Suitable for cable noise reduction in equipment harnesses
• Ideal for ferrite choke use on coaxial cable assemblies
• Used with multiconductor wire in signal integrity mitigation
• Can be used for axial suppression on single‑core conductors
• Suitable for cable noise reduction in equipment harnesses
What frequency range does it target for interference reduction?
It attenuates disturbances in the 25MHz to 100MHz band, focusing on mid‑to‑high frequency noise.
How is it applied to wiring during assembly?
It is slipped axially over cable or wire to form a choke around the conductor for suppression.
What regulatory substance standards does it meet?
The component conforms to RoHS and REACH substance restrictions.
What material is used for magnetic performance?
The core uses 4W620 ferrite composition selected for its magnetic characteristics in the specified frequency range.
