1) Measurement parameter: 10 kHz, 0.25 mT, 100 turns, room temperature.
A value is measured acc. to IEC62044-2. An appropriate wringing of cores with polished surface is used to improve
L
reproducibility of the measurement. (It is recommended to rub the mating surfaces themselves six times in a circular or
elliptic arc that matches the core profile before measuring A value).
