LOW FREQUENCY FERRITE EMI CORES
FOR ROUND CABLES & WIRING HARNESSES 300 KHZ TO 30 MHZ OPTIMIZED
PART NUMBERING SYSTEM EXAMPLE
All impedance values for high frequency cores are NET; NET impedance is impedance of the
ferrite core only. All impedance contribution from the test wire and fixtures has been removed.
This catalog lists a limited sample of available parts. Custom parts are also available..
