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 using Coilcraft SMD‑A fixture in Agilent/HP 4284A impedance analyzer. 3. DCR measured on a micro-ohmmeter and Coilcraft CCF858 test fixture. 4. SRF measured using Agilent/HP 8753D network analyzer 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.
