The maximum volt-sec rating limits the peak flux density to B�= 200 mT when used in a unipolar drive application. For bipolar drive applications, a maximum volt-sec of two times is acceptable (ΔB 400 mT). 3) B78307A2238A003 Configuration 1 : 4 use pins 8-5 for primary; Configuration 4 : 1 use pins 2-3 for primary
