1 When ordering, please specify packaging code: e.g. A9967-ALD
Packaging: D = 13" machine-ready reel
EIA 481 embossed plastic tape (175 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 per winding of the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc. Inductance of the primary, with three windings connected in series is 90 μH.
3 Peak primary current (with three windings connected in series) drawn at
minimum input voltage. Peak current per winding is 7.0 A.
4 DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Leakage inductance is for one winding and is measured with all other windings shorted.
6 Output is with both windings of the secondary connected in parallel.
7 Ambient temperature range: –40°C to +125°C
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 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.
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
