1 When ordering, please specify termination and packaging codes: e.g. MSS5131-394MLC
  Termination: L = RoHS compliant gold over nickel over phos bronze
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging: C = 7" machine-ready reel
EIA-481 embossed plastic tape (400 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 C instead.
D = 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (1500 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
3 SRF measured using an Agilent/HP8753D network analyzer and a Coilcraft SMD-D test fixture. Details
4 Isat: DC current at which the inductance drops the specified amount from its value without current. Details
5 Irms: Current that causes the specified temperature rise from 25°C ambient. Details
6 Ambient temperature range: –40°C to +85°C with Irms current.
+85°C to +125°C with derated current Derating curve
7 Storage temperature range: Component: –40°C to +125°C
Packaging: –55°C to +80°C
8 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.
9 Electrical specifications at 25°C.
See Qualification Standards for complete environmental and test data.
