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: HA3809-ALD
  3. . Inductance is for the primary, measured at 300 kHz, 0.7 Vrms. For the GA3568-DL inductance is per winding.
  4. DCR for the secondary is with the windings connected in parallel. For GA3568-DL DCR for the primary is with both windings connected in parallel.
  5. Leakage inductance is for the primary windings with the secondary windings shorted
  6. Turns ratios are for the primary (windings connected in parallel for the GA3568-DL) and 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:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
