Notes

When ordering, please specify packaging code: e.g. POE13P-12LD
Inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc.
DCR for the secondary is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is measured between pins 3 and 4 with all other pins shorted.
Turns ratio is with the secondary windings connected in parallel.
1500 Vrms, 1 minute isolation (hipot) from primary and bias to secondary.
500 Vrms, 1 minute isolation between all other windings.

Termination:

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

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
