Notes

Output is of the secondary winding. Output of the bias winding is 12 V, 20 mA.
When ordering, please specify packaging code: e.g. PA6595-ALD
Inductance tested at 250 kHz, 0.1 Vrms, 0 Adc
Peak primary current drawn at minimum input voltage
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance for the primary is with the secondary and drive windings shorted; leakage inductance for the drive winding is with the secondary windings shorted.
1500 Vrms, one minute isolation, primary and bias to secondary and drive.

Termination:

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

Packaging:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (350 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.
