NOTES:

1. Inductance at 0.1 Vac, 10 kHz.

2. Terminating resistor for 1 V out with 10 amps peak in the primary.

3. The operating temperature range includes the ambient temperature and the temperature rise.

4. The temperature rise of the component is calculated based on the total core and copper loss:

Copper loss (W) : Pcu = (Ipk/Ns)²*(Dmax/3)*Rs.

Core loss (W) : Pfe=1.3*10^-17*f(Hz)^1.63*B(Gauss)^2.45

Bmax(Gauss) = 3.75*10⁹*(Ipk*Rt/Ns+Vd)*Dmax/(k*Ns*f), where f is in Hz, k=1 for unipolar and 2 for bipolar waveform. Keep Bmax below 2000 Gauss.

Temperature rise (°C): ~300*(Pcu+Pfe)

5. Reverse polarity parts are available for all turns ratios : P8222T through P8229T.
