CF SERIES
Cylindrical EMI Suppression Ferrites
Suppressors
API's Cylindrical EMI Suppression ferrites provide a cost effective means of reducing common and differential mode EMI. Used to suppress common mode EMI on the internal and external cable assemblies of electronic equipment. Select a ferrite with an inner diameter most closely matching the outer diameter of the wires to be filtered.
Features
• Wide range of sizes with inner diameters from 1.5 mm (0.059 inches) to 23 mm (0.905 inches)
• Precision formed smooth surfaces prevent damage to wire insulation
• Available in API-1 and API-2 material.
• Custom designs available
Applications
• Internal and external computer data and power cables.
**Note – Impedance Testing Impedance is typical, measurement using HP4191A. For CF1-4*1.5*10 through CF2-4.6*1.85*6, based on 1⁄2 turn (4.0") 32 AWG wire. For CF1-7.35*5.1*10 and above, based on 1⁄2 turn (4.0") 19 AWG wire.
