Notes
  1. All outputs are referenced to ground.
  2. When ordering, please specify packaging code: e.g. D1766-ALD
  3. Inductance is for the primary, measured at 200 kHz, 1.1 Vrms, 0 Adc.
  4. Leakage inductance is for the primary and is measured with secondary windings shorted.
  5. 1500 Vrms primary to secondary isolation.

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 (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.
