CYLINDRICAL EMI suppression ferrites from Steward, represented in Australia by RFI Industries , provide a cost-effective means of reducing common and differential mode EMI.
These cores are most frequently used to suppress common mode EMI on the internal or external and external cable assemblies of electronic equipment.
By decreasing the levels of EMI radiated by internal cables, ferrite cores can reduce the cost and amount of EMI overall shielding required to confine EMI within a products enclosure.
A wide range of inner diameters is available from .89mm to 36.5mm to suit varying cable (or cable bundle) sizes. The ferrite cores are manufactured with precision smoothed surfaces prevent damage to wire insulation.
Three different core materials are available to cover the frequency range from 300kHz to 2GHz.
Applications include internal and external computer data and power cables, printer and monitor cables, power supply cables and telecommunication cables.
