Wurth Elektronik WE-AFB Series Ferrite Ring, 20.5mm Height, 11.5mm Outside Diameter - 74270031
This ferrite ring is a magnetic component designed to reduce electromagnetic interference on signal and power conductors. It is intended for use on multiconductor wiring, coaxial lines and wrapped cable harnesses where suppression of conducted noise between 25MHz and 100MHz is required. The component is manufactured from 4W1500 ferrite material and conforms to RoHS and REACH standards for restricted substances.
Features and Benefits:
• High attenuation at 25MHz to 100MHz improves signal integrity
• Ferrite composition 4W1500 provides stable impedance over frequency
• Axial bead format fits along conductor runs for in-line suppression
• Designed for multiconductor and coaxial use reduces common-mode noise
• Ferrite composition 4W1500 provides stable impedance over frequency
• Axial bead format fits along conductor runs for in-line suppression
• Designed for multiconductor and coaxial use reduces common-mode noise
Applications
• Suitable for multiconductor wire noise suppression in assemblies
• Used with coaxial cable to limit interference on RF links
• Ideal for wrapping cable bundles to control conducted emissions
• Can be used for general wire noise suppression in signal lines
• Used with coaxial cable to limit interference on RF links
• Ideal for wrapping cable bundles to control conducted emissions
• Can be used for general wire noise suppression in signal lines
What frequency range does it target for interference reduction?
It is effective across a 25MHz to 100MHz band where impedance increases to attenuate unwanted signals.
Which materials and approvals are relevant for regulatory compliance?
The component uses 4W1500 ferrite material and carries RoHS and REACH approvals.
How is it applied to different cable types?
Its axial bead form permits installation over single conductors, coaxial cores or multiple wires by threading onto or wrapping cables.
What physical clearances are relevant for installation decisions?
Consider the outside diameter of 11.5mm and inside aperture of 5mm when planning cable routing and anchoring.
