Broad Band EMI Ferrite Split / Snap-on Cores in Plastic Cases for Round Cables & Wiring Harnesses
For retrofit and post-assembly operations, Steward offers a selection of “split” cores. 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 and wire assemblies. Black or white plastic snap-on cases provide secure closure of the split cores onto the cable.
Features:
Up to 10 Amps (I MAX) continuous operating capability
Low DCR • Vibration Resistant • Rugged monolithic construction
Small footprint • Excellent retention under bias
Superior impedance vs. frequency characteristics
Economical
Broad range of sizes ( from EIA 0402 up to 3312 )
Broad range of impedance values and current ratings
Lead free & RoHS compliant
High bias current resistant versions (HR) available.
Low frequency and high frequency chip beads now available
Spice Models incorporating DC bias effects available on www.lairdtech.com
