Notes
  1. When ordering, please specify packaging code: e.g. POE120PL-33LD
  2. Inductance is for the primary, measured at 200 kHz, 0.5 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 with the secondary windings shorted.
  5. Isolation (hipot): 1500 Vrms one minute primary and aux to secondary.

Termination:

  • RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations.
