Notes
  1. Inductance is for the primary, measured at 275 kHz, 1.0 Vrms.
  2. Leakage inductance is for the primary winding with the secondary windings shorted.
  3. 1500 Vrms, one minute primary/bias to secondary/drive 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 (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.
