1 When ordering, please specify packaging code: e.g. DA2062-ALD
  Packaging: D = 13" machine-ready reel
EIA 481 embossed plastic tape (400 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 Inductance is for the primary, measured at 375 kHz, 0.6 Vrms, 0 Adc
3 Peak primary current drawn at minimum input voltage.
4 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Leakage inductance is for the primary winding with the secondary windings shorted.
6 Turns ratio is with the secondary windings connected in parallel.
7 Output for the secondary is with the windings connected in parallel. Bias winding output is 14 V.
8 Ambient temperature range: −40°C to +125°C
9 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°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
