Notes
  1. Output of the secondary is with the windings connected in parallel. Bias winding output is 5 V, 20 mA.
  2. When ordering, please specify termination and packaging codes: HA3586-BLD.
  3. Inductance is for the primary, measured at 300 kHz, 0.5 Vrms.
  4. DCR for the secondary is 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 secondary windings connected in parallel.
  7. 1500 Vrms, one minute isolation from primary and bias to secondary.

Termination:

  • L = RoHS tin-silver (96.5/3.5) over tin over nickel over phos bronze.
  • T = RoHS tin-silver-copper (95.5/4/0.5). (Special order)
  • S = non-RoHS tin-lead (63/37). (Special order)

Packaging:

  • 13" reel, machine-ready 
    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.
