Please specify termination and packaging codes: ME3215-104KLC Termination: L = RoHS tin-silver over tin over nickel over silver. 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 (2000 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. Factory order only, not stocked (7000 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc us- ing Coilcraft SMD -A fixture in Agilent/HP 4284A imped- ance analyzer. 3. DCR measured on a micro-ohmmeter and Coilcraft CCF858 test fixture. 4. SRF measured using Agilent/HP 8753D network ana- lyzer and Coilcraft SMD -D test fixture. 5. DC current at which the inductance drops the specified amount from its value without current. 6. Current that causes the specified temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
