Notes
  1. Output of the secondary is with the windings connected in parallel. Bias winding output is 10 V, 20 mA.
  2. When ordering, please specify packaging code: e.g. C1174-ALD
  3. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms.
  4. DCR for secondary is with windings connected in parallel.
  5. Leakage inductance for the primary is with the secondary and drive windings shorted; leakage inductance for the drive winding is with the secondary windings shorted.
  6. Turns ratio is with both secondary windings connected in parallel.
  7. 1500 Vrms, one minute isolation from the primary and bias windings to the secondary.

Termination:

  • RoHS-compliant  260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations. Other terminations available at additional cost.

Packaging:

  • D = 13" machine-ready reel. EIA 481 embossed plastic tape (200 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.
