注释
  1. When ordering, please specify a packaging code: GA3291-ALD. 
  2. Inductance is measured at 300 kHz, 0.6 Vrms, 0 Adc.
  3. DCR for the primary is measured from pin 1 to pin 3.
  4. Leakage inductance is for the primary (pin 1 to pin 3) and is measured with the secondary shorted.
  5. Turns ratio is based on the entire the primary winding (pin 1 to pin 3).
  6. 1500 Vrms isolation from primary to 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.

包装:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (175 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.
