  1. Output of the secondary is with all windings connected in parallel. Bias winding output is 12 V, 20 mA.
  2. When ordering, please specify termination and packaging codes: JA4456-DLD.
  3. Inductance is for the primary, measured at 250 kHz, 0.5 Vrms.
  4. Peak primary current drawn at minimum input voltage.
  5. DCR for the primary and secondary are with the windings connected in parallel.
  6. Leakage inductance is for the primary windings with all the secondary windings shorted.
  7. Turns ratios are with the primary windings and secondary windings connected in parallel.
  8. 1500 Vrms, one minute isolation (hipot) primary and bias to secondary; 500 Vrms isolation primary to bias; 750 Vrms isolation all pins to the core.


  • RoHS-compliant  260°C compatible. Tin-silver over tin over nickel over phos bronze terminations. Other terminations available at additional cost.


  • 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.
