When ordering, please specify **termination** and **packaging** codes: ## **1008LS-103XJLC** - **Termination: L** = RoHS compliant silver-palladium-platinum-glass frit. **E** = Halogen free component. RoHS compliant silverpalladium-platinum-glass frit terminations. 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 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. **Designer’s Kit C336** contains 10 of each stocked value **Core material** Ceramic/Ferrite **Environmental** RoHS compliant, halogen free optional **Terminations** RoHS compliant silver-palladium-platinum-glass frit. Other terminations available at additional cost. **Weight** 38.3 – 41.0 mg **Ambient temperature** –40°C to +85°C with I rms current, +85°C to +100°C with derated current **Storage temperature** Component: –40°C to +100°C. Tape and reel packaging: –40°C to +80°C **Resistance to soldering heat** Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles **Temperature Coefficient of Inductance (TCL)** +100 to +350 ppm/°C **Moisture Sensitivity Level (MSL)** 1 (unlimited floor life at <30°C / 85% relative humidity) **Failures in Time (FIT) / Mean Time Between Failures (MTBF)** One per billion hours / one billion hours, calculated per Telcordia SR-332 **Packaging** 2000/7″ reel; 7500/13″ reel. Plastic tape: 8 mm wide, 0.3 mm thick, 4 mm pocket spacing, 2.0 mm pocket depth **PCB washing** Only pure water or alcohol recommended Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
