1 Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc
2 Ipk: Peak primary current drawn at minimum input voltage.
3 DCR for the secondary is with windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Leakage inductance is for the primary, measured the secondary windings shorted.
5 Output of the secondary. Bias winding output is 12 V, 20 mA.
6 Ambient temperature range: –40°C to +125°C
7 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
8 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.
