Differential-mode and common-mode chokes (DMC and CMC) are key components of electromagnetic interference filters. Accurate impedance knowledge of these chokes allows optimal EMI filter design to meet the conducted emission requirements. An impedance analyzer or vector network analyzer with a fixtur...
