注释
  1. When ordering, please specify packaging code: e.g.CX9721-ALD
  2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
  3. Leakage inductance measured at 100 kHz, 0.1 Vrms, between pins 1 and 2 with all other pins shorted.
  4. 4000 Vrms, one minute isolation from the primary and auxiliary winding to the secondary.

端子:

  • RoHS-compliant. 260°C compatible. RoHS tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations.

包装:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (700 parts 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.
