| 2 | Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc | |
| 3 | Ipk: Peak primary current drawn at minimum input voltage. | |
| 4 | DCR for the secondary is with windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 5 | Leakage inductance is for the primary, measured the secondary windings shorted. | |
| 6 | Turns ratio is with the secondary windings connected in parallel. | |
| 7 | Capacitance measured between pins 3 and 4 with other pins shorted. | |
| 8 | Output of the secondary. | |
| 9 | Ambient temperature range: | –40°C to +85°C |
