Notes
  1. Inductance measured between secondary pins at 10 kHz, 0.1 Vrms, 0 Adc.
  2. Volt-time product is for the secondary, between pin 3 and 1.
  3. For specific questions regarding frequency range, please contact us at [email protected]
  4. Primary current of 40 A causes less than 40°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
  5. Terminating resistance (RT) value is based on 1 Volt output with 40 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
    RT (Ohms) = Vout × Nsec / Iin.
  6. 4000 Vrms, one minute isolation (hipot) winding to winding

Termination:

  • RoHS-compliant. 260°C compatible. Tin-silver-copper over tin over copper over steel (pins 1 – 3).
  • Tin-silver-copper over tin over nickel over copper (pins 4 – 5) terminations.
