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 <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 25°C. Refer to Doc 362 “Soldering
Surface Mount Components” before soldering.
