1	When ordering, please specify termination and packaging codes: e.g. MSS1038T-105KLC
	Termination:	L = RoHS compliant matte tin over nickel over copper. 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 (250 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 (1000 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/HP 8753D network analyzer or equivalent. 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 +125°C with Irms current. +125°C to +165°C with derated current Derating curve
7	Storage temperature range:	Component: –40°C to +165°C Tape and reel packaging: –40°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.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents.
