Wurth Elektronik WE-AFB Series Ferrite Ring, 28.5mm Height, 17.5mm Outside Diameter - 7427009
This ferrite ring provides high-frequency suppression for general electronics. It is manufactured from 3W800 ferrite material and is suitable for attenuation of EMI and RFI within defined frequency bounds. The component is intended for applications requiring Compact magnetic cores where regulatory substance restrictions are relevant.
Features and Benefits:
• Operates effectively across 25MHz to 100MHz for high-frequency suppression
• Composition of 3W800 ferrite provides frequency‑tailored permeability
• Complies with RoHS and REACH enabling restricted‑substance conformity
• Torus form factor reduces radiated interference in assemblies
• Small footprint assists integration into space‑constrained designs
• Composition of 3W800 ferrite provides frequency‑tailored permeability
• Complies with RoHS and REACH enabling restricted‑substance conformity
• Torus form factor reduces radiated interference in assemblies
• Small footprint assists integration into space‑constrained designs
Applications
• Suitable for EMI/RFI suppression in analogue front-ends
• Ideal for noise reduction on signal and power lines
• Used with Compact PCB assemblies requiring choke elements
• Can be used for high-frequency filtering in consumer electronics
• Suitable for General Electronics prototyping and repair tasks

What frequency range does it address?
It is effective from 25MHz up to 100MHz for attenuation of high-frequency interference.
What material characteristics influence performance?
The component is MADE from 3W800 ferrite which delivers permeability suited to mid‑range RF suppression.
What regulatory substance standards apply?
It meets RoHS and REACH requirements for controlled substances.
How does the geometry affect circuit layout?
The toroidal shape concentrates magnetic paths, enabling Compact placement for choke functions.
What size constraints should designers consider?
Designers should account for an outside diameter of 17.5mm and an inside diameter of 9.5mm when planning board or enclosure clearances.
