Notes
  1. Inductance is measured at 1 kHz, 0.05 Vrms.
  2. DCR at 25°C, For other operating temperatures, use this DCR at Temperature calculator.
  3. Terminating resistance (RT) value is based on 1 Volt output with 35 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
    RT = Vout × Nsec / Iin.

Termination:

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