注释
  1. Output of the seconday is with the windings connected in parallel.
  2. When ordering, please specify packaging code: HA3905-CLD.
  3. Inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc.
  4. Leakage inductance measured on the primary winding with all secondary pins shorted.
  5. 1500 Vrms,one minute isolation from primary, auxiliary and reset to secondary;
    500 Vrms, one minute isolation from primary and reset to auxiliary

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.

包装:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (175parts per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
