Notes

Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
Isat: DC current that causes the primary inductance drop of 30% (typ) from its value without current.
Leakage inductance is for the primary winding with the secondary windings shorted.
Isolation (hipot) measured between windings for one minute.

Termination:

RoHS-compliant. 260°C compatible. Tin-silver-copper over tin over nickel over phos bronzes.

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (350 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
