1 When ordering, please specify packaging code: e.g. GA3382-BLD
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, 0.4 V, 0 Adc.
3 DCR for the primary is with the windings connected in parallel.
4 Isat: DC current at which the inductance drops the specified amount from its value without current.
5 Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
6 Ambient temperature range: −40°C to +85°C with (40°C rise) Irms
7 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise)
9 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.
10 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. More info.
