Broadband Split / Snap-on Ferrite Cores for Round Cables

All parts in this category
are RoHS compliant
For retrofit and post-assembly operations, Steward offers a selection of “split” components. Similar in performance to Steward’s one piece core designs, these split ferrite cores provide excellent common and differential mode EMI suppression on round cable assemblies. Lightweight, inexpensive plastic snap-on cases provide secure closure of the split cores onto the cable.
Features
·Internal core diameters from 3.5 mm (0.138") to 19.3 mm (0.760") radius ·Precision formed smooth surfaces prevent damage to wire insulation ·Available in Steward low frequency broad band (27); broad band (28) or high frequency (HF) materials. ·Custom designs available ·Saves valuable PC board space ·The in-circuit impedance may be substantially increased by passing 2 turns of the wire conductor through the ferrite core assembly ·Easy installation
Applications
·Internal and external power cables ·Internal cables between PC boards and data connectors ·Products with limited PC board space available for surface mount EMI components ·Monitor cables ·Power supply cables ·Printer cables ·Digital cameras ·Auxiliary attenuation
