Wurth Elektronik WE-TOF Series Ferrite Ring, 12mm Height, Toroid Core Type - 742701703
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.
Features and Benefits:
• 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
• 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
Applications
• 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
• 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
What physical Interface does it provide for cables?
It is supplied as a toroidal core allowing wires to be passed through the centre for common-mode suppression.
What material characteristics influence its performance?
The component is MADE from 7W380 ferrite, selected for its magnetic permeability suited to interference suppression across the specified frequency band.
Which size parameters define its fit for assemblies?
The part has a 12mm height and a 15mm inside diameter which determine clearance for routed conductors.
How does its frequency range affect filtering choices?
Its defined 25MHz to 100MHz operating band guides placement where mid- to high-frequency noise reduction is required.
