1	When ordering, please specify a packaging code: e.g. WB3010-1-SMLD
	Packaging:	D = 13" machine ready reel. EIA-481 embossed plastic tape (500 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	Impedance ratio is for the full primary winding to the full secondary winding.
3	Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc
4	Ambient temperature range:	–40°C to +85°C
5	Storage temperature range:	Component: –40°C to +85°C Packaging: –55°C to +80°C
6	Resistance to soldering heat (surface mount version): Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
7	Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
