Notes
  1. When ordering, please specify packaging code: e.g. POE60D-12LD
  2. Inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Leakage inductance is for the primary winding with the secondary winding shorted.
  5. 1500 Vrms winding to winding isolation.
  6. Output of the secondary is with the windings connected in parallel. Bias winding output is 12 V, 0.2 A.
  • Designed to remain in continuous mode operation at power levels of 3 Watts and above.

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 (400 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.
