CF SERIESCylindrical EMI Suppression Ferrites

API's Cylindrical EMI Suppression ferrites provide a cost effective means ofreducing common and differential mode EMI. Used to suppress commonmode EMI on the internal and external cable assemblies of electronicequipment.Select a ferrite with an inner diameter most closely matching the outerdiameter of the wires to be filtered.Features

• Wide range of sizes with inner diameters from 1.5 mm (0.059 inches) to 23mm (0.905 inches)• Precision formed smooth surfaces prevent damage to wire insulation• Available in API-1 and API-2 material.• Custom designs availableApplications

• Internal and external computer data and power cables.

**Note – Impedance Testing Impedance is typical, measurement usingHP4191A. 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.
