2. Inductance is tested between pins 4 and 3 at 500 kHz, 0.5 Vrms, 0 Adc.

3. DCR is for each half of the primary and secondary.

4. Leakage inductance is for the primary with both windings connected in

series and with the secondary windings shorted.

5. Based on Bsat of the core at 25°C and number of turns on winding 4-3.

6. Calculated output power based on 150 kHz operating frequency. Power

varies depending on application.

Parts manufactured prior

to December 2011 may be
