注释
  1. Output is for the secondary. Aux winding output is 9 V, 20 mA.
  2. Inductance is for the primary, measured with the windings connected in parallel at 300 kHz, 0.3 Vrms.
  3. Ipk is the peak primary current drawn at minimum input voltage.
  4. DCR is measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Leakage inductance if for the primary and is measured with the windings connected in parallel with the secondary windings shorted.
  6. 1500 Vrms, one minute isolation (hipot) from the primary and aux windings to the secondary

端子:

  • RoHS-compliant  260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations. Other terminations available at additional cost.
