When ordering, please specify termination and packaging codes: e.g. MLC1550-452MLC

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) or
S = non-RoHS tin-lead (63/37).

Packaging:

C = 7" reel, machine-ready reel
EIA-481 embossed plastic tape. Parts per reel data

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" reel, machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked. Parts per reel data

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	SRF measured using an Agilent/HP4291A impedance analyzer and a Coilcraft 16193 fixture. Details
4	Isat: DC current at which inductance drops 20% (typ) from its value without current. Details
5	Irms: Current that causes a 40°C temperature rise above 25°C ambient. Details
6	Ambient temperature range:	–40°C to +85°C with Irms current.
7	Storage temperature range:	Component: –40°C to +85°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.
Refer to Soldering Coilcraft Components before soldering.
