| 1 | Inductance is for the primary, measured at 300 kHz, 0.3 Vrms. | |
| 2 | DCR is for the primary,measured at 25°C with the windings connected in series. For other operating temperatures, use this DCR at Temperature calculator. | |
| 3 | Leakage inductance is for the primary windings with the secondary windings shorted. | |
| 4 | Turns ratios is with the primary windings connected in series (pins 2 and 3 to be connected). | |
| 5 | Ipk: Peak primary current drawn at minimum input voltage. | |
| 6 | Aux winding output is 20 mV. | |
