Notes
  1. Inductance is for the secondary, tested at 1 kHz, 0.1 Vrms.
  2. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  3. Use the following equation to determine the approximate change in output voltage/ input ampere when varying the terminating resistor: Vout / Iin = 0.1 × (RT / 50).
  4. 2500 Vrms isolation (hipot), one minute between windings.

Termination:

  • RoHS-compliant. Tin-silver over tin over nickel over copper terminations.
