Please specify termination and packaging codes: MSS1246T-105KLD 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 (800 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMDA 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 SMDD test fixture. 5. DC current at 25C that causes the specified inductance drop from its value without current. Click for temperature derating information. 6. Current that causes the specified temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
