1 When ordering, please specify termination and packaging codes: e.g. MSS1246T-105KLC
  Termination: L = RoHS compliant matte tin 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" reel, machine-ready 
EIA-481 embossed 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 C instead.
D
= 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (800 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent.
3 DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture.
4 SRF measured using an Agilent/HP 8573D network analyzer or equivalent. Details
5 Isat: DC current at which the inductance drops the specified amount from its value without current.
6 Irms: Current that causes the specified temperature rise from 25°C ambient. Details
7 Ambient temperature range: –40°C to +125°C with Irms current.
+125°C to +165°C with derated current Derating curve
8 Storage temperature range: Component: –40°C to +165°C
T&R packaging: –40°C to +80°C
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.
