Notes

When ordering, please specify packaging code: PL140-114LD
Inductance measured on an Agilent/HP 4284 between pins 2 and 4 at 200 kHz, 0.1 Vrms, 0 Adc.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance measured between pins 2 and 4 at 100 kHz, 0.1 Vrms, 0 Adc with all secondary pins shorted.
1500 Vdc isolation primary to secondary.

Termination:

RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations.

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.

Aux winding:

To order a transformer with an optional auxiliary winding, add an “X” and the turn count after the PL140, e.g. PL140X3-100LB.
Turn counts of 2, 3, 4, 5, 7 and 9 are available for the auxiliary winding.
Transformers with auxiliary windings are not stocked. Call for lead time.
