Notes

When ordering, please specify packaging code: e.g. PA6340-ALD
Inductance is for the primary, at 1 kHz, 0.5 Vrms, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary and is measured between pins 1 and 2 with all other windings shorted.
Capacitance is measured from pins 1,2 to pins 6,10 at 250 kHz, 0.5 Vrms.
Isolation (hipot): 1500 Vrms, one minute from primary and bias to secondary and sync

Termination:

RoHS tin-silver-copper (95.5/3.8/0.7) over tin over nickel over phos bronze.

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). 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.
