  1. Output is of the secondary winding. Output of the bias winding is 12 V, 20 mA.
  2. When ordering, please specify packaging code: e.g. PA6595-ALD
  3. Inductance tested at 250 kHz, 0.1 Vrms, 0 Adc
  4. Peak primary current drawn at minimum input voltage
  5. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. 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.
  7. 1500 Vrms, one minute isolation, primary and bias to secondary and drive.


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


  • D = 13" machine-ready reel
