Laird Ferrite Bead (Cylindrical EMI Core), 13.72 x 30.56 x 13.72mm (0392), 75Ω impedance at 25 MHz, 170Ω impedance at

Broadband Split/Snap-on Cores. These easy installation ferrite cores are designed to reduce electromagnetic interference from being induced or radiated. They are available in a variety of sizes and suitable for applications from 30MHz to 1GHz. These ferrite cores provide excellent common and differential mode EMO suppression on cable assemblies. Rectangular ferrites are suitable for data cables e.g. telephone or signal lines Circular ferrites are suitable for mains cables e.g. on photocopying machines, printers and other office equipment
