1. 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 25°C that causes an inductance drop of <15ꢀ  
(POExx51Q) and <15ꢀ (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 25°C.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
