Please specify termination and packaging codes: MLC1550-452MLC Termination: L = RoHS compliant tin-silver 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. 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. 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4284A LCR meter. 3. SRF measured using an Agilent/HP4291A impedance analyzer and a Coilcraft 16193 fixture. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
