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


Split Ferrite Rings


These split ferrite cores reduce the electromagnetic interference from being induced in or radiated from data and power cables. High attenuation ratings are achieved with the housing design and the special process steps during the ferrite manufacture. The special snap lock makes the ferrite sleeve suitable for use with a variety of cable diameters and once the split ferrite is locked it cannot be opened accidentally.The outer housing is designed to protect the halves of the core from breakage and ensures simple assembly on to cables that are already installed or which have been fitted with connectors. Fixing to the cable with glue or cable tie is optional. Typical applications for these split ferrite cores include data or power lines used in computer technology, terminals, industrial controllers, medical engineering and office machines.
