Fair-Rite Products Corp., Your Signal Solution®, In this video we give a brief example of the effect wire length has on rated impedance values of a ferrite EMI suppression device. When characterizing a core, the wire length should be kept to a minimum to give a more accurate representation of the of the actual impedance that will be added to your circuit.
