NOTES: 1. Inductance at 0.1 Vac, 10 kHz.

2. Terminating resistor for 1 V out with 35 amps peak in the primary.

3. The operating temperature range includes the ambient temperature plus the component 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=1.5*10^-17*f(Hz)1.63*B(Gauss)^2.45

Bmax(Gauss) = 8*10⁸*(Ipk*Rt/Ns+Vd)*Dmax/(k*Ns*f), where f is in Hz, k=1 for unipolar and 2 for bipolar waveform,

Ipk is the input current, Rs is the secondary turns. Keep Bmax below 2000 Gauss.

Temperature rise (°C): ~90*(Pcu+Pfe)

5. Add suffix "T" to part number for tape and reel packaging (i.e. PB0025T).
