1. When ordering, please specify termination and packaging code: SLC7649S-101KLC Termination: L = RoHS compliant matte tin over nickel over copper Special order: 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 (250 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 (1000 per full reel). Factory order only, not stocked. 2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. 3. DCR is measured between the two points indicated on the dimensional drawing. 4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent. 5. DC current at which the inductance drops 20% (typ) from its value without current. 6. Current that causes a 40C temperature rise from 25C ambient. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
