3.To calculate the value of the terminating resistor (Rt) use the following
formula: Rt (Ω) = Vref * N / (Ipeak_primary)
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.
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).
