Notes

Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
Minimum inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 2.6 Adc.
DC current that causes an 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 tin-silver-copper over tin over nickel over phos bronze. Other terminations available at additional cost.

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (500 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
