注释
  1. Output is for the secondary. Bias winding output is 12 V.
  2. Inductance measured at 125 kHz, 0.1 Vrms, 0 Adc.
  3. Leakage inductance is for the primary and is measured with the secondary shorted.
  4. 3000 Vrms, one minute isolation from the primary and bias to the secondary winding.

端子:

  • RoHS-compliant. Tin-silver over tin over copper over steel terminations. Other terminations available at additional cost.
