Notes
  1. When ordering, please specify packaging code: e.g. FA2519-ALD
  2. Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.
  3. Ipk is the peak current drawn at minimum input voltage.
  4. DCR for the primary and for the secondary is with the windings connected in parallel.
  5. Leakage inductance measured on the primary windings with all secondary pins shorted.
  6. Turns ratio is with the primary windings and the secondary windings connected in parallel.
  7. Isolation is from primary and auxiliary windings to secondary windings for one minute.

Termination:

  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations.

Packaging:

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

Soldering

Resistance to soldering heat:
Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
Refer to Soldering Coilcraft Components before soldering.
