1 Packaging: D = 13" machine-ready reel
EIA 481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
2 Inductance is for the primary, measured at 300 KHz, 0.1 Vrms, 0 Adc.
3 Minimum inductance is for the primary, measured at 300 KHz, 0.1 Vrms, 2 Adc.
4 Sec1 DCR for YA8779 is with windings connected in parallel. 
5 Leakage Inductance is for the primary, measured with secondary windings shorted together.
6 Ambient temperature range: −40°C to +85°C
7 Maximum part temperature: +125°C (ambient + temperature rise)
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Resistance to soldering heat: Max three 40 second reflows at +260°C allowing parts to cool to room temperature between cycles.
10 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.
