When leads +260C, parts cooled to room temperature between cycles are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value. Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) 3. DCR is for each winding. When leads are connected in parallel, DCR is half the value.

DC current at 25C that causes the specified inductance drop from its value without current. It is the sum of the current flowing in both windings. 7. Equal current when applied to each winding simultaneously that causes a 40C temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. 8. Maximum current when applied to one winding that causes a 40C temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. 9. Electrical specifications at 25C. Refer to Doc 639 Selecting Coupled Inductors for SEPIC Applications.
