Wurth Elektronik WE-TOF Series Ferrite Ring, 61mm Outside Diameter, 35.5mm Inside Diameter - 74270097
This ferrite ring is a toroidal core designed to reduce electromagnetic interference in cable and wiring systems. It is produced from 4W620 ferrite material and is intended for suppression of EMI within a defined radio‑frequency band. The component is suitable for suppression of common‑mode noise where frequency‑selective damping is required and meets current environmental substance restrictions.
Features and Benefits:
• 25MHz to 100MHz frequency band suppresses high‑frequency interference
• 4W620 ferrite material provides predictable impedance characteristics
• Toroid geometry enables efficient magnetic coupling for single‑turn cables
• Compliant substance profile supports regulated material use
• 12.7mm cross‑section thickness minimises insertion depth demands
• 4W620 ferrite material provides predictable impedance characteristics
• Toroid geometry enables efficient magnetic coupling for single‑turn cables
• Compliant substance profile supports regulated material use
• 12.7mm cross‑section thickness minimises insertion depth demands
Applications
• Suitable for reducing cable noise on power and signal lines
• Ideal for inserted EMI filtering on external harnesses
• Used with single‑pass conductors to lower common‑mode currents
• Can be used for interference mitigation in consumer electronics
• Suitable for retrofit suppression on existing wiring looms

What frequency range is effective for suppression?
The component is specified to operate between 25MHz and 100MHz for targeted attenuation of high‑frequency disturbances.
What material properties affect performance?
The 4W620 ferrite composition determines permeability and frequency‑dependent impedance used to shape attenuation characteristics.
How does the toroidal shape influence installation?
The ring format allows a conductor to be passed through the bore so magnetic flux couples directly, producing impedance without adding series resistance.
Which dimensional limits affect cable routing?
The inner aperture of 35.5mm sets the maximum single‑pass bundle diameter that can be accommodated.
What regulatory substance statements apply to usage?
The part is declared compliant with RoHS and REACH substance restrictions.
