Notes
  1. Inductance shown for each winding. Measurement details are part number specific. See part number page in datasheet for details.
  2. Current flows through both windings connected in series that causes a 40°C rise. This information is for reference only and does not represent absolute maximum ratings.
  3. DCR is specified per winding.
  4. Isolation (hipot) measured for 1 minute.

Termination:

  • RoHS compliant tin-silver over copper.
