When ordering, please specify termination and packaging codes: 1008LS-103XJLC Termination: L =RoHS compliant silver-palladium-platinum-glass frit Special order, added cost: 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 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 (7500 parts per full reel). 2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286A impedance analyzer with Coilcraft-provided correlation pieces. 3. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture. 4. SRF measured using an Agilent/HP 8753D network analyzer with a Coilcraft SMD-D fixture. 5. DCR measured on a Cambridge Technology Micro-ohmmeter. 6. Current that causes a 15°C temperature rise from 25°C. Because of their open construction, these parts will not saturate. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. For part marking data see Color Coding section. Designer’s Kit C336 contains 10 of each stocked value Core material Ceramic/Ferrite Terminations RoHS compliant silver-palladium-platinum-glass frit. Other terminations available at additional cost.
