| 2 | Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value. | |
| 3 | DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 4 | SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value. | |
| 5 | Leakage Inductance is for L1 and is measured with L2 shorted. | |
| 6 | Isat: DC current, at which the inductance drops the specified amount from its value without current. It is the sum of the current flowing in both windings. | |
| 7 | Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise. | |
| 8 | Irms, one winding:
Current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Determine temperature rise. |
