1	When ordering, please specify packaging code: e.g. GA3372-ALD
	Packaging:	D = 13" reel, machine-ready  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 measured at 250 kHz, 0.7 Vrms, 0 Adc
3	Ipk is peak primary current drawn at minimum input voltage.
4	DCR for the secondary is with the windings connected in parallel.
5	Leakage inductance is for the primary and is measure with the secondary shorted.
6	Turns ratios are with the secondary windings connected in parallel.
7	Output is with the secondary windings connected in parallel. Auxiliary winding output:10 V, 20 mA.
8	Ambient temperature range:	–40°C to +125°C
9	Storage temperature range:	Component: –40°C to +125°C Packaging: –55°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.
