1 Inductance is measured at 1 kHz, 0.05 Vrms.
2 DCR at 25°C, For other operating temperatures, use this DCR at Temperature calculator.
3 Volt-time product is based on 2000 Gauss.
4 Terminating resistance (RT) value is based on 1 Volt output with 35 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
RT = Vout × Nsec / Iin.
5 Ambient temperature range: −40°C to +85°C
6 Storage temperature range: Component: −40°C to +85°C
Packaging tubes: −40°C to +80°C
7 Electrical specifications at 25°C
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
