1	When ordering, please specify packaging code: e.g. FA2707-BLD
	Packaging:	D = 13" reel, machine-ready  EIA-481 embossed plastic tape (200 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, 0.2 Vrms, 0 Adc
3	Ipk is peak primary current drawn at minimum input voltage.
4	DCR for the primary and the secondary is with windings connected in parallel.
5	Leakage inductance is for the primary and is measured with the secondary and drive windings shorted.
6	Turns ratios are with the primary and secondary windings connected in parallel.
7	Output is with the secondary windings connected in parallel. Auxiliary winding output:10 V. Drive winding output: 5.5 V
8	Ambient temperature range:	–40°C to +125°C
9	Storage temperature range:	Component: –40°C to +125°C T&R 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.
