This ferrite ring is an EMI suppression toroidal component designed to reduce high-frequency interference on wrapped cable, multiconductor wire and coaxial cable within typical electronic interconnects. Made from 3W 800 ferrite material, it provides targeted attenuation across a specified band while remaining Compact for inline placement on wire bundles and individual conductors.
Features and Benefits:
• 25 to 100MHz attenuation band reduces mid-range RF interference
• Toroidal geometry minimises external magnetic field leakage
• 3W 800 ferrite composition improves common-mode suppression
• 6mm height enables tight axial accommodation on harnesses
• Compact form assists retrofitting without connector removal
• Toroidal geometry minimises external magnetic field leakage
• 3W 800 ferrite composition improves common-mode suppression
• 6mm height enables tight axial accommodation on harnesses
• Compact form assists retrofitting without connector removal
Applications
• Suitable for wrapping cable to suppress conducted noise
• Used with multiconductor wire in harness assemblies
• Ideal for coaxial cable to reduce RF emissions
• Can be used for general wire EMI/RFI suppression
• Suitable for toroidal EMI filter installations in equipment
• Used with multiconductor wire in harness assemblies
• Ideal for coaxial cable to reduce RF emissions
• Can be used for general wire EMI/RFI suppression
• Suitable for toroidal EMI filter installations in equipment
What frequency range does the material effectively target?
It is specified to operate between 25MHz and 100MHz for interference reduction.
How does the component attach to cable bundles?
Its toroidal shape allows wires to be passed through the central aperture for direct coupling without additional hardware.
What are the aperture and external diameters relevant for cable fit?
The central opening measures 12.7mm and the outside diameter is 21.2mm for sizing cables and bundles.
Which material characteristics influence performance?
The 3W 800 ferrite grade is selected for its magnetic properties that enhance common-mode choke behaviour.
Are there constraints on axial space when installing?
The ring has a height of 6mm, informing clearance requirements on wire harnesses.
