Wurth Elektronik WE-TOF Series Ferrite Ring, 11.5mm Outside Diameter, 5mm Inside Diameter - 74270113


This ferrite ring is a toroidal component designed to reduce electromagnetic interference in cable and wiring assemblies. Manufactured from 4W620 ferrite material, it operates across higher-frequency ranges to attenuate noise within targeted bands. The component is intended for integration where compact, passive EMI mitigation is required and conforms to chemical regulatory standards for material content.

Features and Benefits:


• 25 to 100MHz suppression range improves high-frequency noise attenuation
• 4W620 material provides stable permeability across the intended band
• Toroidal shape enables uniform impedance around conductors
• RoHS and REACH compliance reduces material-restriction risk

Applications


• Suitable for inline cable noise reduction in assemblies
• Ideal for EMI filtering on signal and data lines
• Used with power supply harnesses for conducted emissions control
• Can be used for retrofit suppression on existing wiring looms

What frequency span does it effectively attenuate?


It is specified to target interference from 25MHz up to 100MHz.

Which material is used and why is it relevant?


The core is MADE from 4W620 ferrite, chosen for its magnetic characteristics across the stated frequency band.

How does the toroidal form influence installation?


The ring's doughnut geometry permits a conductor to be passed through the internal aperture for choke action without additional mounting.

Are there environmental substance declarations associated with the component?


The component meets RoHS and REACH chemical-restriction standards.
