1. Inductance shown for each winding. Measurement details are part
number specific. See part number page for details.
2. DCR is specified per winding.
3. 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.
4. Isolation (hipot) measured for 1 minute.
5. Electrical specifications at 25°C.
