1. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc
2. Leakage inductance tested at 100 kHz, 0.1 Vrms
3. Isolation tested between primary and secondary on all parts and
between primary and auxiliary on Z9260-AL.
4. Primary to secondary turns ratio specified with secondary
windings connected in parallel.
5. Operating temperature range -40°C to +85°C.
6. Electrical specifications at 25°C.
