Inductance is for the primary, measured on an Agilent/HP 4284 at 100 kHz, 0.1 Vrms, 0 Adc. 3. Leakage inductance measured between pins 2 and 3 at 100 kHz, 0.1 Vrms, 0 Adc with pins 8 and 5 shorted. 4. Isolation (hipot) measured between windings for one minute. 5.DC current that causes an inductance drop of 30% (typ) from its value without current 6. Electrical specifications at 25°C.
