Wurth Elektronik WE-AFB Series Ferrite Ring, 25mm Height, 11.5mm Outside Diameter - 74270032
This ferrite ring is designed to reduce electromagnetic interference on cable assemblies and wiring runs. It is intended for axial placement on conductors where suppression of high-frequency noise is required across a defined band. The component is manufactured from a 4W620 ferrite material and meets applicable substance restrictions, making it suitable for integration in systems with regulatory constraints.
Features and Benefits:
• 25 to 100MHz operational band reduces interference across VHF frequencies
• 4W620 material offers targeted impedance at high frequencies
• EMI suppression axial ferrite bead form improves series choke performance
• RoHS and REACH compliance simplifies material selection processes
• Axial configuration supports straightforward in-line mounting on cables
• 4W620 material offers targeted impedance at high frequencies
• EMI suppression axial ferrite bead form improves series choke performance
• RoHS and REACH compliance simplifies material selection processes
• Axial configuration supports straightforward in-line mounting on cables
Applications
• Used for wrapping cable to suppress radiated noise
• Suitable for ferrite ring for coaxial cable choke
• Can be used for multiconductor wire ferrite core installations
• Applied to wire runs where high-frequency EMI ferrite ring control is needed
• Suitable for ferrite ring for coaxial cable choke
• Can be used for multiconductor wire ferrite core installations
• Applied to wire runs where high-frequency EMI ferrite ring control is needed
What conductor sizes will pass through the component?
The internal aperture measures 5mm, permitting single conductors or small bundled leads to pass through for suppression.
Which frequency range will experience greatest attenuation?
Peak suppression performance is specified between 25MHz and 100MHz where the material exhibits significant impedance.
What material properties affect performance?
The 4W620 ferrite composition provides permeability and loss characteristics tuned for higher-frequency choking action.
Is this suitable for placement on shielded cable?
It can be fitted onto coaxial cable where an axial ferrite choke is required to reduce common-mode emissions.
