2. Inductance is for the primary, measured at 300 kHz, 0.1 Vrms, 0 Adc.
3. Minimum inductance is for the primary, measured at 300 kHz, 0.1 Vrms,
3 Adc.
4. Leakage Inductance is for the primary, measured with secondary
windings shorted together.
5. 1500 Vrms, one minute isolation (hipot) from primary to secondary.
6. Electrical specifications at 25°C.
Connect pin 1 to 2, pin 3 to 4, pin 5 to 6,
and pin 7 to 8 on the PC board
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
