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 airflow when both one turn windings
connected in parallel.
3. To calculate the value of the terminating resistor (Rt) use the following
formula: Rt (Ω) = 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 above by 2.
5. Add “T” suffix to the part number for Tape & Reel packaging, (i.e. P8222T).
