High Frequency Ferrite EMI Cores
Split, Snap-On Ferrite Cores in Plastic Cases
00 MHz to  GHz Optimized
For retrofit and post-assembly operations a selection of high frequency EMI “split” cores are offered. Similar in performance
to one piece cylindrical core designs, these split ferrite cores provide excellent common and differential mode high
frequency EMI suppression on round cable and wire assemblies. Black plastic snap-on cases provide secure closure of
the split cores onto the cable or wire bundle.
- 0A2 part number suffix designates black plastic case. Additional colors may be available, please inquire with Laird Technologies’ customer service.
