NOTES: 1. The temperature of component (ambient temperature plus temper-ature rise) must be within the
specified operating temperature range. 2. The maximum current rating is based upon temperature rise of the component and represents the
DC current which will cause a typical temperature rise of 40°C with no airflow when both one turn windings connected in parallel. 3. To calculate value of terminating resistor (Rt) use the following formula: Rt (W) = Vref * N / (Ipeak_primary) 4. The peak flux density of the device must remain below 2000 Gauss. To calculate the peak flux density for uni-polar current use following formula: Bpk = 37.59 * Vref * (Duty_Cycle_Max) * 105 / (N * Freq_kHz) * for bi-polar current applications divide Bpk (as calculated ...
