2. Inductance is for each winding, measured at 100 kHz, 0.1 Vrms,
0 Adc.
3. DCR is for each winding.
4. DC current at 25°C that causes the specified inductance drop from
its value without current.
5. Current that causes the specified temperature rise from 25°C
ambient.This information is for reference only and does not
represent absolute maximum ratings.
