1 When ordering, please specify termination and packaging codes: e.g. WA3097-ALD
  Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or
S = non-RoHS tin-lead (63/37) over copper.
  Packaging: C = 7″ machine-ready reel.
EIA-481 embossed plastic tape, 250 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 C instead.
D = 13″ machine-ready reel.
EIA-481 embossed plastic tape, 400 parts per full reel
2 Inductance and Q measured at 150 MHz, 0.1 Vrms, 0 A using an Agilent/HP 4291A impedance analyzer or equivalent with an Agilent/HP 16193A test fixture.
3 SRF measured using an Agilent/HP 8753D network analyzer or equivalent and a Coilcraft SMD-D test fixture. Details
4 DCR measured at 25°C using a micro-ohmeter. For other operating temperatures, use this DCR at Temperature calculator.
5 Irms: Current that causes a 15°C 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 +125°C with Irms current.
7 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +140°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.
11 Temperature coefficient of inductance: +5 to +70 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
