Wurth Elektronik WE-AFB Series Ferrite Ring, 28mm Height, 16mm Outside Diameter - 7427005
This ferrite ring is a passive magnetic component designed to suppress electromagnetic interference in general electronics. It is manufactured from 4W620 material and intended for use across a defined high-frequency band. The component supports regulatory substance limits and is suitable for integration where Compact suppression of conducted and radiated noise is required.
Features and Benefits:
• Operates across 25MHz to 100MHz to attenuate high-frequency noise
• Composed of 4W620 material to provide frequency-stable performance
• Conforms to RoHS and REACH to limit restricted substances
• Torus geometry offers consistent impedance for choke applications
• Sub-type ferrite core enables straightforward assembly in circuits
• Composed of 4W620 material to provide frequency-stable performance
• Conforms to RoHS and REACH to limit restricted substances
• Torus geometry offers consistent impedance for choke applications
• Sub-type ferrite core enables straightforward assembly in circuits
Applications
• Suitable for EMI suppression in power conversion modules
• Used with signal lines to reduce conducted interference
• Ideal for incorporation into consumer electronics assemblies
• Can be used for noise attenuation in communication devices
