Packaging: |
D = 13"
machine-ready reel
EIA 481 embossed plastic tape (175 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. |

Inductance is for the primary, measured at
200 kHz, 1.1 Vrms, 0 Adc |
|
3 |
Ipk: Peak primary current
drawn at minimum input voltage. |
|
4 |
Leakage inductance
is for the primary winding with the secondary windings shorted. |
