Wurth Elektronik Ferrite Ring Toroid Core 12 mm, For: EMI Suppression 15 mm ID 12 mm OD

This ferrite ring is designed to suppress electromagnetic interference in electronic assemblies operating across a selected high-frequency band. It performs noise attenuation for signal and power lines within defined frequency limits and is intended for insertion where a toroidal ferrite core is required to reduce interference in circuits.

• 25MHz minimum frequency for targeted noise attenuation
• 100MHz maximum frequency for wideband high-frequency suppression
• 7W380 material offering tailored permeability for EMI control
• Toroid core form factor enabling efficient cable coupling
• 12mm height delivering Compact footprint for constrained spaces

• Suitable for suppression of EMI on signal lines
• Used with cable bundles to reduce radiated noise
• Ideal for high-frequency filtering in assemblies
• Can be used for attenuation in 25 to 100MHz noise

It is supplied as a toroidal core allowing wires to be passed through the centre for common-mode suppression.

The component is MADE from 7W380 ferrite, selected for its magnetic permeability suited to interference suppression across the specified frequency band.

The part has a 12mm height and a 15mm inside diameter which determine clearance for routed conductors.

Its defined 25MHz to 100MHz operating band guides placement where mid- to high-frequency noise reduction is required.
