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.
