注释

When ordering, please specify packaging code: e.g. POE13F-12LD
Inductance is for the primary, measured at 250 kHz, 0.3 Vrms.
DCR for the primary and for the secondary are with the windings connected in parallel.
Leakage inductance is for the primary windings with the secondary windings shorted.
Turns ratios are with the primary the secondary windings connected in parallel.
1500 Vrms isolation primary and bias windings to secondary windings.
Output of the secondary is with the windings connected in parallel. Bias winding output is 12 V, 20 mA.

端子:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

包装:

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.
