Notes
  1. When ordering, please specify packaging code: GA3431-BLD.
  2. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.
  3. DCR for the secondary is per winding.
  4. Leakage inductance measured between pins 3 and 4 with all secondary pins shorted.
  5. Turns ratio is with the secondary windings connected in parallel.
  6. 1500 Vrms isolation from primary and bias to secondary;
    500 Vrms isolation from primary to bias, tested for one minute.
  7. Output is with the secondary windings connected in parallel. Bias winding output: 5.0 V, 20 mA (GA3430); 3.3 V, 20 mA (GA3431).

Termination:

  • RoHS tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost.

Packaging:

  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (250 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.
