CF1-16*9*17

s or ss re pp Su CF SERIES Cylindrical EMI Suppression Ferrites 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 CF1-4*2*10, based on 1⁄2 turn (4.0") 32 AWG wire. For CF1-9.5*4.8*20 and above, based on 1⁄2 turn (4.0") 19 AWG wire.
