Wurth Elektronik Ferrite Ring EMI Suppression Toroidal Ferrite 20 mm, For: Multiconductor Wire, Wrapping Cable, Wire,

This ferrite ring is an EMI suppression toroidal component designed to reduce electromagnetic interference on cables and wires within mid-frequency ranges. It is intended for use where common-mode noise mitigation is required on multiconductor, wrapped and coaxial conductors. The component is manufactured from a 3W800 material optimised for the stated frequency band and sits between conductor turns to attenuate interference without modifying cable routing.

• High impedance provides improved common-mode attenuation
• Operates across a defined mid-frequency band for targeted suppression
• Toroidal form factor allows unobtrusive installation on cables
• Material composition supports magnetic loss characteristics for filtering
• Through-hole design permits simple retrofitting to existing harnesses

• Suitable for ferrite bead on multiconductor wire
• Ideal for wrapping cable noise reduction on assemblies
• Used with coaxial cable where interference suppression is needed
• Can be used for general wire noise reduction in harnesses
• Suitable for inline EMI filtering on cable runs within 25 to 100MHz

It functions effectively from 25MHz up to 100MHz for mid-band interference attenuation.

It is intended for multiconductor, wrapped cable, single wire and coaxial cable installations.

The 3W800 magnetic material provides the loss characteristics required for EMI filtering in the specified band.

The ring allows the cable to pass through its centre, enabling straightforward placement without soldering or connector changes.

The component exhibits an impedance of 550 Ω for evaluating insertion into suppression networks.
