A9786-AL_	150	36 – 75	2.5	60.0	1.25	0.90	62.5 (1 - 3)	0.91 (5,6 - 9,10) 200 (4 - 11)

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	Primary/secondary isolation 1100 Vdc.
5	Ambient temperature range:	–40°C to +85°C
6	Storage temperature range:	Component: –40°C to +85°C T&R packaging: –40°C to +80°C
7	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.
8	Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
