Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (150 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). 2. Inductance is for the primary, measured at 250 kHz, 0.5 Vrms, 0 Adc. 3. Leakage inductance is for the primary with the secondary and aux windings shorted. 4. DC current at 25C that causes an inductance drop of <15% (POExx51Q) and <15% (POExx40Q) from its value without current. 5. Output is for the secondary. Output of the aux winding is 12 V, 30 mA. 6. Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering.
