1 When ordering, please specify packaging code: e.g.A9786-ALD
Packaging: D = 13" machine-ready reel
EIA RS-481 clear plastic tape (125 parts per full reel).
B = Less than full reel
In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 Inductance measured on an Agilent/HP 4284 between pins 1 and 3 at 250 kHz, 0.1 Vrms, 0 Adc.
3 Leakage inductance measured between pins 1 and 3 at 100 kHz, 0.1 Vrms, 0 Adc with all secondary pins shorted.
4 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Primary/secondary isolation 1100 Vdc.
6 Ambient temperature range: −40°C to +85°C
7 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
8 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.
9 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. Other solvents
