注释
  1. Output of the secondary is with the windings connected in parallel. Bias winding output is 15 V, 20 mA
  2. When ordering, please specify termination and packaging codes: GA3271-ALD.
  3. Inductance is for the primary, measured at 250 kHz, 0.1 Vrms.
  4. DCR for the primary and for the secondary are with the windings connected in parallel.
  5. Leakage inductance is for the primary windings with the secondary windings shorted.
  6. Turns ratios are with the primary the secondary windings connected in parallel.
  7. 1500 Vrms, one minute primary to secondary isolation.

端子:

  • L = RoHS tin-silver over tin over nickel over phos bronze.
  • T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • S = non-RoHS tin-lead (63/37). (Special order)

包装:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (200 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.
