Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc. 2. Peak primary current drawn at minimum input voltage. 3. Leakage inductance is for the primary and is measured at 100 kHz, 0.1 Vrms with all other windings shorted. 4. Turns ratio for the secondary is with the windings connected in parallel. 5. Isolation is from the primary to all other windings, tested for one minute. 6. Electrical specifications at 25°C.
