Please specify termination and packaging codes: MSS1246-105MLC Termination: L =RoHS compliant matte tin over nickel over phos bronze. 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 (200 parts 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 (800 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent. 3. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture. 4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 5. DC current at which the inductance drops 10% (max) from its value without current. 6. Current that causes the specified temperature rise from 25C ambient. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
