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 DCR for primary is per both windings connected in parallel, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Leakage inductance is for the primary winding with the secondary windings shorted.
5 Turns ratio is with the primary windings connected in parallel.
6 Output of the auxiliary winding is 10.2 V.
7 Ambient temperature range: −40°C to +85°C
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +125°C
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 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.
