Wurth Elektronik WE-TOF Series Ferrite Ring, 20mm Height, 35.5mm Inside Diameter - 74270191


This ferrite ring is designed to reduce electromagnetic interference in high-frequency circuits. It is fabricated from 4W620 ferrite material and intended for through-hole use where axial placement around conductors is required. The component operates across a defined frequency band suited to suppression tasks and complies with common material safety standards for use in manufacturing environments.

Features and Benefits:


• Suppresses EMI across 25MHz to 100MHz, improving signal integrity
• High-permeability 4W620 material reducing common-mode noise
• Toroid core geometry enabling efficient choke formation
• Meets RoHS and REACH, aiding material compliance efforts

Applications


• Suitable for EMI filtering on signal lines
• Ideal for choke components in high-frequency boards
• Used with cable harnesses for conducted emission control
• Can be used for interference reduction in consumer electronics

What frequency range does it target for suppression?


It provides attenuation within the 25MHz to 100MHz band based on material response and geometry.

What mounting arrangement is intended for this component?


It is designed for through-hole placement, allowing conductors to pass through the toroidal aperture.

Which material properties affect its suppression performance?


The 4W620 ferrite composition offers permeability and loss characteristics suited to high-frequency EMI damping.

Which environmental standards are met by the component?


The component conforms to RoHS and REACH restricted-substance requirements.
