This ferrite ring is a passive EMI suppression component designed to reduce electromagnetic interference on cables and wires within its operating band. It is manufactured from a high-permeability ferrite material and intended for installation by wrapping around conductors to attenuate unwanted noise between 25MHz and 100MHz in a variety of cable assemblies.
Features and Benefits:
• 25 to 100MHz attenuation range for targeted noise suppression
• 3W800 ferrite material offering consistent permeability performance
• Axial bead geometry enabling straightforward wrap-on installation
• RoHS and REACH compliant composition supporting regulatory needs
• 3W800 ferrite material offering consistent permeability performance
• Axial bead geometry enabling straightforward wrap-on installation
• RoHS and REACH compliant composition supporting regulatory needs
Applications
• Suitable for wrapping cable to suppress radiated emissions
• Ideal for coaxial cable ferrite bead implementations
• Used with multiconductor wire EMI filter arrangements
• Can be used on single or bundled wire harnesses
• Ideal for coaxial cable ferrite bead implementations
• Used with multiconductor wire EMI filter arrangements
• Can be used on single or bundled wire harnesses
What conductor sizes can it accommodate?
Its inside aperture measures 7.3mm so conductors or bundles must fit within that opening.
How does the component affect high-frequency signals?
It attenuates interference primarily in the 25MHz to 100MHz band by presenting impedance to common-mode currents.
What materials compose the magnetic core?
The core is produced from a 3W800 grade ferrite formulation chosen for its magnetic properties.
What external dimensions determine mounting clearance?
The component has an outside diameter of 15.5mm and a total height of 28.5mm.
