| 1 | Inductance is for the secondary, measured at 15.75 kHz, 1 Vrms. | |
| 2 | DCR at 25°C, For other operating temperatures,use this DCR at Temperature calculator. | |
| 3 | Volt-time product is for the secondary, based on 2000 Gauss. | |
| 4 | Terminating resistance (RT) value is based on 1 Volt output with 35Â Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout × Nsec / Iin. |
