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 ltered. 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 12 turn (4.0 ) 32 AWG wire. For CF1-7.35*5.1*10 and above, based on 12 turn (4.0 ) 19 AWG wire.
