NOTES:
1. The temperature of the 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 air flow when both one turn windings
connected in parallel.
3. To calculate the value of the 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 a uni-polar current use the
following formula:
Bpk = 14.29 * Vref * (Duty_Cycle_Max) * 10⁸ / ( N * Freq_kHz)
* for bi-polar current applications divide Bpk as calculated above by 2.
5. For RoHS compliant parts add suffix NL to the part number.
6.Add T suffix to the part number for tape and reel packaging.
