Split Ferrite in Plastic Case with 0.8 mm Air Gap and Snap-in Lock


STAR-GAP snap ferrite sleeves feature a pre-fixing and cable protection system allowing for quick and easy assembly. A low reduction of impedance is ensured by the low magnetic saturation of the material in high DC current applications.

These ferrite sleeves are ideal for RF applications and are suitable for high-speed data lines such as CAT5, LAN network and higher. They are also suitable for EMI problems between 100 MHz up to 2.5 GHz and can reduce USB 2.0 disturbance.

Please note, the safety key (74271) is sold separately. Refer to 815-0021 to order the key.

2 windings provide the best impedance/performance

STAR GAP snap ferrites feature a patented ’defined air gap’

Up to 100 MHz data signals are not affected

These snap ferrites minimise SMPS and fast circuit interference

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.
