1. When ordering, please specify packaging code:

POE13F-12LD

Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (200 parts per

full reel).

B = Less than full reel. In tape, but not machine ready. To have a leader and

trailer added ($25 charge), use code letter D instead.

2. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms.

3. Peak primary current drawn at minimum input voltage.

4. DCR for the primary and for the secondary are with the windings connected in parallel.

5. Leakage inductance is for the primary windings with the secondary windings shorted.

6. Turns ratios are with the primary the secondary windings connected in parallel.

7. Output of the secondary is with the windings connected in parallel. Bias winding output is

12 V, 20 mA.

8. Electrical speciﬁcations at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
