1 Inductance is for the primary, measured at 150 KHz, 0.1 Vrms, 0 Adc.
2 Peak primary current drawn at minimum input voltage.
3 Leakage inductance is for the primary winding with the secondary windings shorted.
4 Turn Ratios specified are with no core gap.
5 Output is for the secondary. Output of Aux1 winding is 20 V, 35 mA. Output of Aux2 winding is 5 V, 35 mA.
6 Ambient temperature range: −40°C to +125°C
7 Maximum part temperature: +165°C (ambient + temperature rise)
8 Storage temperature range: Component: −40°C to +165°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.
