1 When ordering, please specify packaging code: e.g. IFLY0012LD
  Packaging: D = 13" machine-ready reel
EIA RS-481 clear plastic tape (200 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 is for the primary, measured at 100 kHz, 1.0 Vrms.
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Ambient temperature range: −40°C to +85°C
5 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: –40°C to +80°C
6 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.
7 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..
