1. The maximum current rating is based on temperature rise of the component and represents the dc current which will cause a typical temperature rise of 40°C with no airflow.
2. To calculate the value of the terminating resistor (Rt) use the following formula: Rt (Ω) = Vref * N / (Ipeak primary)
3. The peak flux density of the device must remain below 2000 Gauss. To calculate the peak flux density for a uni-polar current, use the following formula:
Bpk = 64.9 * Vref * (Duty Cycle Max) * 105 / (N * Freq kHz) — (for bi-polar current applications divide Bpk as calculated above by 2).
